Rode Bloomer today. It was *fun*. Regarding signage, I have a couple of suggestions.
Heading for marker 25, there is a fork in the trail and the little bike arrow points to the left. This takes you out on a two track that has *another* fork, but no sign/arrow telling you which way to go (although right is the correct choice). If you go right at the first fork, you stay on the singletrack and won't get lost. So, this should be cleared up.
At the fork that leads you to the lung buster, there is a sign with bike arrows going each way. My suggestion is to add signs telling you what you're getting into. For example, the left arrow would be accompanied by a sign that says, "Lung Buster." The right arrow could say, "Easy," or something like that.
I forgot what it's called, but the crazy switchbacks down the hill right after the upper ridge--when you get to the bottom, there are several options for a way to go, but no sign. Probably a right arrow pointing to the lower ridge trail would be helpful. I didn't even know this trail was there until I rode with the guys today and followed them. I thought you just dumped out onto the doubletrack.
So, those are my signage suggestions.
Today was a *great* day to ride.
