4th day off

I'm staying in Pittsburg for my day off. I need to goto the library to plan my route from here. The TransAm goes a little north, I want to head south. Also I got a slow leak in my back tube I need to patch (first flat). And while I'm at it I'll rotate my front and back tires. The back has a ton of wear, while the front has almost none. Plus the weather is supposed to be windy and cold.
