So I'm visiting Tulsa, OK from AL, and realized that Team Covenant is here! I looked online and saw that they have game nights for X-Wing on Tues. and Wed. What time do people usually show up to play? Would love to get to play some locals!

The store's Facebook page is probably your best bet for getting in touch with staff/local players:

Not sure many folks show up on Tuesday, Wednesday is the most popular night. Store is open from 5-11pm, and there's probably the most people there between 6:30 and 10ish. Friday and weekends occasionally see groups, but that's more hit and miss. If you were around till next saturday, they're having a little Wave 11 event, where you have to include a wave 11 pilot and upgrade in your list.
