Is the limestone section fine for a hybrid bike with roadie tires (700 x 25 Gatorskins)?

I've never ridden a non-paved rails-to-trail before on a non-mountain bike. I'm planning on riding more than 20 miles worth, and don't really want to bring my FS mountain bike. The trail should be dry, not muddy.

Thanks.

EDIT: I read that the entire tail is wheelchair accessible, so I guess that answers my own question.
