Within 100 yards of my building - and once riding down Central Ave. (aka construction zone 2006-2008) - I noticed my rear tire get squishy. Never a good feeling. I glanced down quickly and could immediately tell that I had a flat. I had to ride it out for about 20 yards until I could make a turn to get off the road. Once I was safely off of the road, I dismounted and inspected the tire. I quickly noticed a small button-sized nail head, flush with the tread of my tire. That thing was WAY down there...
I carried my bike inside my building, and proceeded with my normal routine. Throughout the day, as time allowed, I tinkered with the tire to see what sort of fix would be required to get myself home. I pulled the nail out and gave the pedals a few cranks to get the rear wheel spinning, which would allow the slime sealant to flow to the hole and plug it up. Once I had my bike up to my office, I turned the bike upside down, and propped the rear wheel (by running a pencil between the spokes and resting on the chainstays) with the puncture on the bottom. This would allow gravity to do it's work and get the sealant to pool up around the puncture.
About mid-afternoon, I tried pumping some air into the tire, but it just wouldn't hold air. This is why you should ALWAYS carry a spare tube.
Once work was over, I changed into my riding clothes, and went to work replacing the tube with a new one. Now, my spare tube is just a standard tube - no sealant or extra thick walls - so I knew I would have to be extra careful on the way home. After unhooking the tire from the rim, I pulled out the old tube and inspected the inner casing of the tire to make sure there was no glass or any other objects embedded in there that would tear my replacement tube. ALWAYS check the inside of a tire when changing tubes - there are few things worse than having your spare tube pop after installing it because there was a thorn or shard of glass stuck inside your tire.

Sure enough, I made it home safely. Tonight I will take off the rear wheel and pull out the spare tube I installed today. I will replace it with a brand new slime tube so I am not riding a bike that is simply bandaged - I'm going for the surgery, not the first aid! I will take some pictures and post those tomorrow.
That's all I will say today. I am working on writing a 4-part Guide to Bike Commuting that will be published on a few friends' websites. When they are all finished, I will also post them on this blog - so be sure to be on the lookout for those. And be on the lookout for rusty nails!
It will take more than a flat tire to stop me! Long live the Velorution!
