Ditto. No-brainer win. Takes a lot o' admin headache off a club volunteer (managing memberships, unfun 'indoors stuff') -- more time to Have Fun, Drink Beer, Ride, Trails, Beer, Ride, Beer. And we all get to support a Great org, FORC, along with another Great org, IMBA. Not to diminish a dime, but it seems a great Value returned for a small cost of a few dues dollars lost each day ($2.63? - in beer money that's 1/3 of a craft sixer). That could be offset with membership mgmt time/effort no longer necessary and realigned to fund raising or donation solicitation. Money does not seem to be a FORC problem. If it ever does, raise cost of event entries by $2.50 or $5.00 or whatever makes sense -- people will still come.
That's my backseat $0.02 Oh and hell doesn't everyone know about the socks?!?!?
