You talk like this happens all the time there when you saw it once. I am sure it has happend in the woods in your area as well as it could happen anywhere. That was my point about sticking to LPC's or GRC's, but now that i think about that those are probably not safe either, just look at some of the rest area's that were closed down for those reasons. As far as deleting your log for it they should have at least emailed you about your concern and maybe you should have done the same and sent him an email with your concerns as well. Being so concerned about this did you report the activity to the local authorities, or post comments about it on South portlands land trust web page? I agree with you that it is not something I would want anyone to stumble across, but you take that chance anywhere you go, not just clarks pond trail where you saw it one time.
