never ride far from home without your cell phone....went for a ride yesterday after work and nearing my turnaround point I saw another rider in the distance...I said to myself "I'm going to pass him/her before I make the turn"....I started mashing and soon I was 20 yards behind the rider and closing....then I heard it....psssttttttttt....front tire went flat....no problem, I have a spare tube and CO2 in my wedge....pull over, and while changing my tire another rider pulls over and asks if I need anything, he says "I dont have any air, but I do have a cellphone"...I say not to worry I'm about done and with that I fill my tire and off he goes....I get ready to go, get on the bike start off and 10yards later....pssssstttt....I pinched the tube putting it on....now I'm SOL....I'm on the service road of the highway and cars are passing like no tommorrow yet no one stops....after about 20 minutes a 19-20yr old kid pulls up after exiting past me, coming back on the ther side of the highway, then turning around to get to me....rolls down the window and asks "you need help dude??"...lends me his cell, I call the wife and thank him for being kind enough to stop...20 minutes later I'm back at my car swearing I'll always bring the phone from now on, and be ALOT more careful when changing a tube on the side of the road.
