It’s in Patapsco State Park, Maryland, more specifically these trails are in Catonsville and the trail head is on South Hilltop Road. Check out the MTB Project app, these trails are on it. The first trail shown on the video is called “Drugs”. Good luck finding it.
Thanks man, that trail is soo fun!! Yeah we should ride sometime, I will have to get your # next time I see you at the shop so we can ride. Just wish the weather would cooperate!
