I have a friend who is need of a training center
Which teaches beginning to advanced agility or flyball. In the Harrisburg area. or surrounding towns. I hope someone can email me with some ideas.
TIA

In that area, I only know Dauphin DTC. There is also an Obedience Club, and probably others nearby.

They have agility, but I don't know if they cover USDAA. S/he could hook up with folks there who do both AKC and USDAA to learn the differences, maybe in home practice sessions or building rentals. Plenty of people in NJ do both. They started flyball classes this weekend.
Other clubs are closer to Philly area. A Lab I bred, Laylagrove Lady of Lorien OA OAJ AD AS MJ AG AR FD, recently added her FDX title while competing with her owner/handler Barbara Rake. You can locate flyball teams for region 15 on

I love the names of some of the flyball teams!
Tell your friend to have fun, but build up jump height slowly!
