Bring some casual clothes if you plan on going to the bar there, or for lounging around in the evening. Boots/Good Shoes and a sturdy belt are important. I think we had one guy using a reloader, nobody cared. WiFi there is not free, and cell service is not the best but doable. I don’t think any of my class paid for WiFi.
You will leave with more stuff than you came with so if you have a little extra space in your bag that would be good.
