My opinion. NO!!!
I have been there several times. And every time I go, I say never again. Until someone talks me into it again.
The Good~~Great trails. Lots of variety. Plenty of mud. Directional loop. 30+ miles. Good food.
The Bad~~Way too many riders. In the thousands. You may wait in line a couple of hours just to get it. Not kid/timid rider friendly. Too many GNCC think-they-are's that will pass you where there is not room to pass. Too much of your riding is done in idle. There are soo many bikes that it just isn't fun (to me).
The Adena Sportman's Club that run the ROTR rides uses them as a fund raiser. They use the money to purchase more land, equipement etc. I have rode it with club members. It is a fantastic place to ride...
