Miserable day in the woods

It had the makings of a beautiful day.  The weather was great, only in the 50's although a little windy.  I went up to the tower.  At 2:30 two kids on ATV's drive by and went up the hill.  It was the same one from the last time.  At 3:30 they headed back down the hill...this time they saw me.  They weren't happy and as they passed they revved their engines and started talking loudly...I think they called me a hand job.  At 4:40, as it was prime time, a guy walking a dog skirted my perimeter until dark.  I have a funny feeling it was one of the same kids from the ATV or at least someone that the ATV kids told I was there.
