We are preparing to leave for our first trip to the Fort and I have a question about the type of bikes to bring. My son just graduated high school and he got a Trek bike for his gift (no not anywhere near the high line models, but it still cost a pretty penny. He is thinking about taking his bike to the Fort. I am not so wild about that idea, thinking that it would be better to take his old ( and cheapr bike). I'm worried about that nice bike sitting in the rain at the boat dock all day while we are in MK. I am also afraid it could walk away. I hate to think that way, but it does happen unfortunately. I'm curious. Do you take their nice bikes (like a Trek), or do you take a less expensive bike to be safe. I know not everyone has two bikes, but in this situation we have yet to sell his old bike.
