Last weekend I attended a church camp-out for the fathers and sons in my area. While riding around in the back woods of dog valley having a great time as far away and as removed as man can get from civilization, I felt the ominous feeling of rocks on rims as all the air had bled from my tire. It just takes one sharp piece of glass at the right angle to ruin your day and make you walk 30 miles to get help. Luckily for me I wasn't riding alone and Mark helped me get the bike back to camp. I was totaly unprepared for a flat tire that day. 

Point is we need to be ready for flat tires on this next trip.
