I would have done the same. I would give up one evening of hunting to make try and make sure they don't comew back also. I do agree with the others about it probably not affecting the deer though. I hunt the property across the road from me that my landlord owns and it is a big opening in the middle of the woods on a hill and we have a guy in there clearing a bunch of stuff up and leveling it out with a dozer. I went up there on our skip loader yesterday and he said he was surprised he hasn't seen any deer watching him and I figured they would be long gone, but I ran the loader to the back side (this area is about the size of a football field and a half) and saw a piece of scrap metal back in the trees (spring tornado) so I walked over to get it and jumped 4 does sitting about 30 yrds in that were watching in curiosity. So don't always assume atv's/machinery will run off your game.
