Very casual and fun event for some quick seat time, maybe some test & tune if you need to make and test adjustments.
Show up and pay. No timing. No course working! Just line up and take a run... then line up and take another. Jeff & I went to one and each of us took 10 runs... in about an hour and a half. Decided that was sufficient (entry fee was $30 for that one) and called it a day. You could easily get in 20-30 runs if you stuck with it.
