Tacos will be pastor, asada, and chicken (assuming the store doesn't run out) and I'll have onion, cilantro, pico, cheese, some hot sauces, etc.
I'll happily make quesadillas for any kids (or overgrown children like myself).
Run schedule varies based on rigs that show up, but there is typically an easy run and a not easy run on Saturday. The easy run is any stock 4x4 or better. The hard run is usually 33s and a locker (or a driver). If there's enough to justify, could be a third run.
Sometimes there's a Friday...
