Actually, I was beginning to think there might be a connection between increased deer sightings, and the loss of deer habitat due to shenandoah construction. Now that their old home is "cleared" they are wandering around looking for a new one. just a thought. and not a judgement call on whether or not racetracks or deer take precidence, so don't assume!
I know that at a track day I went to last year at RoeBLING Road they had a short mention of the turtles that like to make their way on to the track during the course of the day !
a couple of years ago at an Ed Bargy track day at RRR, the red flag came out because near T6 there were some huge birds that wouldnt fly away. They looked like big pelicans but were I think migratory birds (maybe Geese?)
