The "hills" at DP aren't anything close to what is at HP.
They have one track, but I've only been on it a couple of times.
The best way to have fun on the DP hills is to go down them FAST. With the curves, ruts, leaves (wet days in the Fall can get interesting), roots, and sticks it makes the easy hillclimbs fun for those needing a little challange. Sounds like we need to plan a trip to Highland Park now that the kids are bigger.
