got a tire scare.

I for some reason decided to drain the fresh tank. Which is just above and kind of favoring the back side of the axles. Well, as I lay there watching it drain. I was looking right down the length of the tandems. I saw a BULGE in the back tire. WHAT?. I was already planning how to change it, and was just staring at it kind of upset like. Then as I got back some. I noticed the tire was sitting on a couple rocks right where it bulged out. Soon as I move the TT. Bulge will be gone.
