Santa Clara had a good program-too bad you missed out. I have met a good proportion of very professional types who went there, contrary to what its position on the page of US News would indicate.
Your list of things to worry about indicates that law school is very likely to become the wrong choice for you after a semester of study. I guarantee you that when you start competing in your classes, the last thing you will be worried about is the snow outside or the gun laws or anything else. You need to be focused on going somewhere that has a program for teaching what you want to learn. If you are stuck on quality of life at this stage, be prepared to enter the regional law market...which is abysmal. (But then again, so is the national market, but that's new at least....)
The question you should be asking yourself is: What do I want to learn, and what kind of work do I want to do? Tailor your school choice accordingly. When you start there, spend all your time worrying about what's in those casebooks instead of worrying about how much it sucks that you can't shoot guns there.
Then, go get a job that will pay for your hobbies, including guns, and that makes you happy.
