That's a fantastic idea. Here is the schedule: https://www.basenjinationalspecialty.com/schedule/
For a spectator I think agility is hands down the most interesting. Unfortunately it's on the weekend so perhaps not the best for meeting breeders (if you care). This also doesn't seem to be Basenji only, so if you want to see Basenjis then probably not the best.
Lure coursing can be fun and there is a lure seminar on Monday. So Monday for that and Tuesday for Puppy and Veteran Sweepstakes?
