I never liked running on a track (or a machine, for that matter)... Having run both cross-country and track, I found I liked the "real" ground better than anything.

You should check out the cross-country course, over here behind Fountain Park. (Just make like you're driving to the ALF and then veer right and park.) It has rolling hills, straightaways, marked distances, and even a turn past the water station on the back 9 of the golf course.

It's so easy on my totally defective, screwed-together, missing-several-pieces knees.
