[clarification needed] Approximately 26 pro riders are invited in each category, with additional competitors coming from qualifying events such as the Roxy Snow Classic.
Chicken Jam has a devoted following and although a "private" event is generally open to those with well behaved children who leave their dogs at home.
Adults are not necessarily required to behave as well as their children, although they should be music loving, peaceable, and generally happy in spirit.
They should also bring a fine potluck dish, ice for the coolers, and plan on sleeping in the field if they imbibe.
