I imagine if you do 1 region you will have 10 events. no Jan and no Dec? Why not have all 3 opens and the invite as part of the schedule. that leaves 6 events to add.

here are my thoughts

feb. Folsom, oroville, Collins any of those could be fun.

march Eastman would be cool, but a lot of rules. if eastman dont work the 1 of the above

april Coyote open
May Clear Lake Open
June Delta
July Delta Open
Aug. Delta Night
Sep. Delta
Oct. SCBBBC Clear Lake
Nov. Naci
