Wow, I also had an experience with dirtbikers this year. We have a lease and a part of the land is a 6 acre parcel that borders a house i used to rent. No one in the lease ever hunted it and it was money in the bag for an early season doe and 3 straight years I bagged a buck from the same stand around Veterans day. Well I moved 2 years ago but still hunted the spot. I went to check my setup a few days before the season and heard a bike pretty loud. I figured it was a new renter on his property. Not 50 yards into the woods i see a new trail cut thru the whole woods just torn up by bikes. I caught a glimse of this guy just tearing up the area about 50 yards from my stand. I was so upset! Since I rented there before, I know the land owner made it perfectly clear the woods were leased. I couldnt catch up with the guy and let the president of our lease know. I hunted the stand two seperate mornings without seeing a deer. going to take the stand down tomorrow. So so upset with the situation
