My cycle to work takes me along 6 miles of the Central Arizona Project Canal (CAPC). I'm kept out of the water by an 8 foot fence. This fence is also troublesome for the wildlife that are in the track which are trying to get out of the way of the bike. They are mostly desert cottontails, quail, and lizards. Eventually they find a hole in the fence and dart through before I catch up to them. The quail remember that they can fly and take off at the last minute.
This morning a large lizard took off next to me and kept pace for about 100 yards. It never found a hole and eventually just stopped. I couldn't work out if he'd stopped because he was exhausted and had run out of steam or just didn't consider me a threat anymore.
