I picked up this bike about a week ago It's a vintage Rockhopper series from Specialized, I think from the late 90's.

Sat in a garage for probably close to two decades until the owner finally decided to get rid of it, so it's in great condition.
I bought an older bike because I wanted to cut my teeth on something simple and cheap. I plan on using it for generally getting around, but also to beat up on the trails. What are the opinions on an older bike like this with less aggressive geometry for having some fun on the trails? I'd like to get better at bhops and general technical navigation. I"m not expecting it to blow my mind on the technical stuff, but can it hack it?
