Just got back from Columbus; spent about two weeks there.
I must have gone to Rays about five times. Only about a 2 hr drive; easier than going to Diablo from base! They have some FUN lines, and everyone is nice. They have a deal with Donatos/Dominoes (forget which) so you can have pizza delivered there for cheap.
If you have a hardtail, bring it and slam the saddle and throw on some good flats. If you have a park bike / DJ / BMX, even better. Singlespeed is by far preferable; less stuff to worry about! A lot of the place revolves around flow anyways; no need for granny.
If you have some icky full squish 3x9 bike... well, bring it anyways, but at least drop the saddle.
They rent out some really nice bikes for only $10 a day. I fell in love with the 21.5 BLKMRKT Three57, a dirtjump/urban hardtail. Prolly picking up one soon. They also rent GF hardtails, BMXs, a Predator, and even some full squish bikes (dunno why). Same price, and you can change bikes throughout the day as long as you don't do it too often.
Difficulty is nice, the beginner room progresses really well. The rest of the place is really well thought out. All the jumps are either tabletops or rollers, so you don't have to worry as much about clearing them all on the first try. Pump sections are amazing. People of all skills ride there, I saw a few families / old people, a lot of guys like me, some BMX pros and even ran into Lenosky (again?!? haha).
If you do BMX they have a really nice semi-secluded bowl, halfpipe, and grind room area. As well as huge jumps with a foam pit.
Everyone else is right about Cleveland, the rest of the city blows. Hard.
I was talking to the staff about expanding, trying to convince them to make a a place somewhere in Jersey or even NYC. They would make a killing.
Can't wait to go there again!
