i mean, like where there is grass where there should be a sidewalk, but there's a line of dead/missing grass and it's basically dirt.

the park i'm talking about is schnabel park in san antonio. i found this utube video of a guy on a bike. what kind of bike is he riding? mountain bike or hybrid bike?

can i take a hybrid bike on here, like the quick 4?
if not, can i take a mountain bike on the road to get here?

and basically just going up and down the street to get some exercise. i don't need to get anywhere quickly, i just want to have fun doing it.

the hybrid bike didn't feel right, are they all pretty much the same? use 700x35c tires?
can i jump a curb on a hybrid bike and not destroy it withing a year?

i told the guy at the shop i wanted something to ride around the neighborhood, but i didn't know the existance of said park, until i found it on google maps. now i'm thinking if i can ride my bike(on the road) over to the park and go exploring it's trails.

i found this other video, it looks like they have mountain bikes:

can i ride a mountain bike on a normal paved street, potholes included?

thank u.
