There will be one this spring in Raccoon St Park,I don't know any positive date yet.I have been trying to take the course for almost a year now. I was signed up last july and they cancelled it a few days before because the course was too muddy. Then I signed up again for nov. but I broke a couple ribs the week before and had to cancel.Hopefully I will make it to the next one! Check out ATV Safety Institute.
Check with local dealer or clubs if you have one near by. Sometimes dealers will have someone come and put classes on. DCNR is not supposed to do them for the public anymore because it takes money away from the private sector.
