I'd be signing up for this if it was a month or so later. At this time of the year riding's a bit "make hay while the sun shines". So I'd rather say no, at this point, than yes and then bail out ride morning.

Hmmm, what I'm trying to say is great idea, but a bit early in the MTB season for making firm dates.

What's that Swiss saying about April weather? "April, April, mach was du willst".
