Since orienteering clubs generally allow you to be a member of more than one club at a time, you can be like PinkSocks (Orienteering Kansas) and BigWillyStyle (Sammamish) and write in your first club for all of your events!
Phew ! Good point, thanks!
Yeah, you can be a member of however many clubs you want. However, according to Orienteering USA, you can only have one primary membership at a time.
For me, I have a lifetime membership with Orienteer Kansas, and they are my primary club (which is why I have them listed as my club, why I wear pink & blue, etc). I also have a Cascade membership, too (required as part of the board). We also had a BAOC family membership in 2013 because it was cheaper to get a family membership and pay club rates for the Team Trials event that year.
Because OK is my primary, I can't run at a US Relay Champs for Cascade, and I also can't vote on behalf of Cascade at the annual O-USA meeting.
Some people like to stick with their first club. Some people like to change it up. I'm big on loyalty, which is why I rep OK. (That said, I'm running a race in Kansas on Sunday and I'll we wearing Cascade colors, for geographical diversity!)
