Have fun in Tyler. Don't arrive during rush hour if you're not familiar with a swarm of individuals that drive like with a sense of themselves, and not much else.
Seriously, and whatever you do.. On broadway(69) by the mall, do not leave your blinker on, because someone will assume you're turning, and will pull out infront of you. The roads are slick when it rains, and that doesn't bother anyone.
Also, there's a nifty gunshop called The Shootist right next to Hastings Bookstore/music/video/etc, but it's kinda hidden in the corner so expect to miss it. Hastings parking lot is fine for it. If you're coming from the north, it's on the south side of the city, so drive straight through. No one really drives on copeland too much, except during school hours, so that's a good way to get past the mall area of Broadway. AFAIK there aren't any gunranges where you can simply walk in.
El Chico's Mexican Restaurant is pretty good still, and if you are coming from the north, you can get to Copeland and take that all the way to 323(it continues past 323, into a residential neighborhood), take a right, and it's across the street from the highschool.
BTW, don't hang out in the North for too long if you don't absolutely have to.
Honestly.. It is a despicable place, with a particularly bad methamphetamine problem, and crime statistics that would really make you understand why you need a gun in the first place. The most likely place you'll learn about the crime statistics is when you see firsthand just what this post was about. Your odds go up as you move away from South Broadway.
