Nick,
Nice work! Two suggestions:
1. Print a big poster of your last picture with arrows pointing to the ruts. Tell the trail poachers that their actions will require CORP to repair a lot of the trail and possibly force Dane County to close the trail permanently. Put the poster next to the taped off area. "Stay off until CORP says it is OK. We worked very, VERY hard for this. Don't screw it up for us!"
2. We need to push riders to an alternative area to ride when the trails are muddy. Madison Metro Sewage District gave an OK last year to ride in the wildlife observation area off Southtown Rd and Moorland Rd. It is accessible from the Cap City Trail and roughly 2 miles away. These are fire lane gravel roads that they plow all winter. I know it is not single track or downhill, but it is outside, along the Yahara River, and indestructible. OK, it is flat. Give directions on the new poster.
Sorry I will miss the big fundraiser. Not planning to leave the desert until temps exceed 110F. Actually, that could be by March 28.
