A virtual alleycat is a lot of work but it's a lot of fun to put together and, I hope, to participate in. Contestants participate in a virtual scavenger hunt where they click through to various websites to find the next checkpoint. The final checkpoint gets you into the contest.
I plan to contact several blog owners via email for their permission to ride through, but drop me a note here if you'd like to be a checkpoint. For an idea of how it worked out last time, visit my original virtual alleycat page. I might take Dave's suggestion and make this a virtual charity ride instead. I'll talk with him and give it some thought.
