What's with all the pee bottles by the side of the road?

This is a phenomena I only recently became aware of. Apparently men, (I hope only men) pee in empty water bottles and toss them out the window of moving vehicles on interstate highways. There are an incredible number to be seen. Someone could study the health of the motoring public by urinalyses. If the color is any indication there are some very sick people out there. The sheer volume suggest getting hit in the head with one isn't completely out of the realm of possibility.

Exploded retreads and black shock cords are also all over the place. I've already destroyed one inner tube on this ride from retread wire.

Today's ride was a bit easier. I'm now in Quartzite, AZ and in a McDonald's for the second time in three days. God help me.

Occasionally, it's necessary for us to ride on the interstate highways, but only when there is no alternative. It's not as bad as it sounds since the shoulders are pretty wide so far. It's far more unnerving for the dual hay trucks to pass on two lane roads. They don't seem to like to share.

Off to look for the hostel and a UPS store to ship more stuff. Although I've been shipping things back, the bags are still very full. Go figure.
