You guys are fucking tripping. I'm from Tulsa. It's mellow, sometimes a bit too mellow, but you just have to make an effort to find shit. The local music scene here is fucking dope. Lots of great improv jazz and hip hop shit going on every night. Sick dive bars or classy wine and cocktail spots depending on your tastes. There are great people here, and I've never really been anywhere as welcoming, especially concerning the skate scene. You won't get vibed if you show up at the park, you'll probably get handed a beer or two and you'll be in the pack from then on. We've got 3 concrete parks and an old metal park scattered around town, and they're all good for different reasons, and then there are parks in surrounding towns just a thirty minute drive away.
Tulsa has shit public transit, isn't very pedestrian friendly, and if you don't have a car you'll hate your life. And so you can't buy strong beer on Sundays. Go to the bar, settle for 3.2 beer, or plan ahead. Also, it is the buckle of the Bible Belt. Good luck. If you're not a doucher and you like beer i could probably arrange a tour and tasting at Prairie Artisan Ales too.
