If the schedule matches the PNW one that I am going to on Whidbey Island, Friday is check-in, car washing and then a private gathering/Dinner/Social hours. Saturday is the "Drive" and then another private gathering. Sunday morning is the goodbyes and every one heads home.
The National meets run thru Sunday with events. There are just regionals this year.
Next year should be Southwest and Southeast for regionals.
Texas has one coming up also this year.
