Hey everyone, been a little over a year since I moved and thought I'd update this a little.
First off, Arlington has a ton of trees, like even if I hadn't seen a post claiming there were no trees I'd still be like, "holy crap, that's a lot of trees".
I haven't had the time to explore as much as I'd like but here's some basic impressions. Arlington isn't too bad to live in. I got an apartment up a little north of Jerry World and can usually make it to campus in 15 minutes or less and really close to I30 if I need to go anywhere. As some mentioned, not a lot to do here other than the Cowboys, Rangers, and UTA athletics but pretty easy trip to Dallas, Ft Worth or any of the other Mid Cities. It's obvious they're trying to build up the area around Jerry World into more of a destination but still have a long ways to go.
I've enjoyed Ft Worth, pretty cool mix of historical and modern, and whoever suggested Rodeo Goat, thanks, really enjoyed that place. Don't recommend if you hate the smell of cow, but really good burgers. On the Dallas side I haven't been able to make it over there as much. Deep Ellum was cool and ate somewhere over there that I don't remember the name of that was really good.
Traffic kind of sucks but it's a big city so not unexpected. 820 around the Arlington/Ft Worth border is terrible. Avoid at all costs. I30 can be bad, but outside of the busiest part of rush hour usually moves at least ok. Haven't had many issues with 360 but haven't taken it much during high traffic times. 157 can be a shitshow, but that's more about people being idiot drivers than anything.
