Thanks for your reply!
Just got back from LBS and they put SLIME Gel in the front tire & a SLIME LINER AND GEL in the back tube. I don't get why the back tire got extra stuff??
Anywho, I'd just like to say that up until the flat, it was an ABSOLUTE blast! I did have to walk up & down this one huge hill, but other than that, I stayed on the bike!
