Everything really? I'm most familiar with Earth cuisine, but I've been trying to learn some other planetary cuisines the last few years in space. I'm good at pancakes and anything that involves a grill or an open flame really.
Barrel racing is riding a horse really fast around a course with barrels set up on it? I'm not describing it well. It's an old Earth rodeo sport. the goal is to go through the course as fast as possible.
