Yesterday, 6/4/15, at about 6:30pm I passed a group of dirtbikes and quads all parked outside of this house. They were fueling up. One dirtbike pulled out right in front of me and went the wrong way down Carmel and appeared a few minutes later on Whalley ave on the sidewalk. I'm not sure if I have the address exactly right, the house might have been a little farther north. I wasn't about to stop and figure out exactly where I was. The house was definitely on the east side of the street. I'm also not saying that all 6-8 dirtbikes I saw yesterday belong to this house, but I would bet that there is at least one in the back yard.
