Thanks for the info! I guess I missed the "trail conditions" part of the madcitydirt home page and went right to the forums.
If the bikers were close enough, I definitely would have said something, but they were climbing the hill in the woods & I was on the hiking trail. I have experience building trails, so it did irritate me. The gravel was soft, so I can imagine what the single track was like.
In fact, I just became an official IMBA-CORP member today... cheers!
Can't wait to get my t-shirt! 8)
