Here in KY the Lou-val quarry bike trails are news to me. I'll check with some
cavers who live near there. Sounds like adventure for some, just as the very
popular "slides for life" are today, if one never had the opportunity to do a
slide like erry Raines had set up on his place years ago. All
Being an abandoned mine, no impacts at all and certainly nothing like
the mine itself may have had.
I'd say any potential for impacts would be about the same or less than
the NSS had at the 2007 convention doing its photo salon and banquet in
a limestone mine remade as a warehouse.
