Steve, you just knocked it out of the park. I agree 100% with everything you just said, although I know split run groups have been a point of contention. If we do 3 runs in the am and 2 in the afternoon I think it's worth it, the only caveat is that we have to have enough workers to cover the course but you know that better than I do. I agree though, on low turnover days, 3 run groups is probably ideal and a 20 minute (really it's 30 but you have to say 20) after group 2 is needed so they can get cars into grid to run and grab a quick bite. Plus, we've been able to do 5 runs at pretty much every event due to attendance.
We're stepping up our social marketing with Facebook event invitations every event, posting on other forums, and I even saw that Brice posted a notice on Triad's FB page to let them know we'll be in their backyard in less than two weeks at Piedmont so I think we have that covered.
I can't really think of any one thing that's going to get people back out other than more business cards but we need to incentivize the distribution of them or they end up in the bottom of gloveboxes and never get passed out. I'm willing to make more if this gains any steam.
Here's an idea: Who ever wants THSCC Auto-x business cards gets them at the meeting, writes their name on the back. When a novice redeems the $5 discount card at the event, the person who's name is on the back gets a free entry (or maybe discounted if it's not a nightmare for T&S)? Just a thought... Maybe we need to trade the revenue generated by a veteran non-officer for that of the income generated by a first-timer in hopes they'll return, as that's the only way it helps the club's bottom line.
I got a really
nice laminated card from the S2KCA.com (yeah, I'm a little biased

) on my wiper after getting off the bike up at Fall Lake and was the heck back in the woods of all places and would have never know the club/forum existed.
Edit: one last thing, I have buddy and his wife that I pursuaded to came back out in a new NC Miata at last year's Jimmy V and won't be back out. I asked him why and they told me they were miserable after being stuck working group four in the heat, which turned out to be a long one. They're both pretty healthy cyclists too that are actually used to the heat. Maybe, long work groups are part of the reason? Who knows? Just a thought...
