Best SHTF rifle for urban/suburban setting?

So many to choose from. If you could only chose one rifle for a suburban broad based SHTF scenario, what would it be?

I'm near the Gulf Coast and had the pleasure of riding out Katrina with a Sears double barrel shotgun (Savage?) and a Sig 9mm. I carried that sig everywhere. Then I got a Romanian AK clone that was ok, but later sold it bc although dead nuts reliable, it wouldn't hit Minute of Basketball accurately.

Now, I have two AR15s in 223, one is extra lightweight, lots of Magpul, iron sights only, but with a flashlight quick detach; another with EAo Tech and cheapo flip to side 3 power magnifier and heavier barrel. I also have a wicked sweet M1A shorty, very nice. And a Rem 700 deer rifle in 30-06, w nice Nikon scope.

What should I keep in the trunk of my car? What should I keep by my bedside? I have a SW 9mm in the car now, a Glock 40 cal in my bedside nightstand, but a rifle seems better for SHTF.

Anyways, I definitely appreciate everyone's opinions and advice. Thanks!

How to get more photography clients? Details inside?

I've been doing photography for about 6 months. I know that's a short time and I know everyone and their dog thinks they are a pro photographer these days. However, I do get clients, just not very many and not very consistently. I get an occasional engagement shoot and I've booked two weddings and shot one so far. My facebook page is facebook.com/marqellealexanderphotography I've seen another girl ask this and get berated and I'm just here for constructive criticism. If you were looking for a photographer and came across me, what would make you pass me up. I charge 120 for family, friends, maternity, and newborn pictures.ni charge 80 just for single pictures. And I was charging 400 for weddings but had to stop doing weddings due to my work schedule. What jumps out at you negatively or positively? Btw I have a Canon Rebel XS that I haven't used yet. The photos on my site were with my nikon D50

What should I do if my camera is still not focusing properly after a service?

I got a Nikon d7000 for Christmas and noticed it wasn't focusing properly. It's all over the place. I use single point focus and put it right on the subject and it is not even close to sharp. I've reset the camera, sent it in to be looked at, tried adjustments on the lens (can't think of the term right now). I previously had a d5000 and never once had a problem. At what point will Nikon just give me another new camera? If they couldn't fix it the first time i don't feel that they will this time. It's very noticeable to me. Can anyone shed some light please?

What dslr camera to buy?

I've been fastenated with photography and decided its about time I get a DSLR. Any recommendations on what to buy. I'm on a budget of less than a grand and wodnt mind buying used. Im leaning to Nikon and Pentax right now. I'm a person who is willing to learn and take the time to do things manually so I probably won't be using a lot of automatic features. Also do you recommend buying used. Where should I buy from to get a good price I'm thinking just amazon but I don't know. Thanks

My nikon d7100 is always taking soft photos?

The past month or so all of my photos have been coming out soft… I don't know if I damaged the camera somehow but they were very sharp when I got the camera which is only about eight months old. I'm taking it to nikon shortly but want I check if I've made some dumb setting mistake unintentionally… Or other reasons a camera would act up a bit?

Tips for traveling UK?

This question is aimed at those who have traveled through Europe or possible live somewhere in the UK. I am attending a 15 day school tour throughout August via 4Seasons. I am from Africa and have never traveled out of Africa, as a result I don't really know what is required to pack etc. Please ray answer the following questions:

1. What kind of travel bag should I pack with clothing etc? Am I going to walk long distances where a wheelie bag will be more convenient?

2. Back pack? I can't decide what kind of backpack to take. I will be traveling with a Nikon camera with 2 external lenses as well as an iPad. I also was wondering if a moon bag is needed for money, valuables etc.

3. Shoes? I don't want to take more than 2 pairs from a space perspective. I am packing comfortable walking shoes but should I take boots?

4. What kind of plugs do I need to take?

5. Will there be wifi in most places? Is it possible for me to buy a sim for my ipad and buy data there?
