fatdaddy, you will see all of the conitions you mentioned, but i don't think he will have any trouble on a ttr 110. you and your son will have a blast, ranlam will show you guys a great time riding.
sledhd & fish i would guess that gas stops will be within 30 miles of each other so there should be nothing to worry about, i can get over 80 miles out of a tank of gas on my wr400 so if we need to i can pull my fuel line and give up enough to get someone to the next gas stop if needed.
man i can't wait, it's going to be a great ride!!!
