This is an amazing experience!! It is not just a fun experience but it is very educational! I am 73 and my wife is 63! WE didn't have any problems with the bikes! Our guide Gator ( John ) was an 11 on a ten scale! He could write a book on customer service! WE were laughing most of the time! You even get to give yourself biker names! Of course my wife came up with Mutt and Jeff and I was MUTT!!! We are going again when we go to Austin in the Spring!! Thanks GATOR!!!
