Try to get friendly with some cooks on friday night and they might invite you back to lend a hand or be a taste tester on Saturday. Most teams are very focused on the job at hand on Saturday and don't have alot of time to be chatting.
If your realy adventurous, call the person in charge of the event and ask if any teams need help. They can almost always hook you up with some team that wont mind an extra pair of hands helping out.
Some people are like Slinkys, they are good for nothing but can still bring a smile to your face when you push them down the stairs.
Down to one lonely ol' Bandera.
