First wipe out ever!

Due to a left knee injury I've not been commuting every day like I used to (only 4 times since Jan-12)

This AM I was making a right turn in a parking lot road (near end destination) and the wheels when out from under me. I was fine except for rash on right knee, bike OK, lost the computer and top plastic cover off of left brifter.

It really puzzles me as I did not think I was going fast, road was clean. There is a shallow dip on corner due to two concrete gutters that go across each road at corner. Other factors may have been me being off of bike so much.

Anyway its my first wipeout in over 10k mi. My main annoyance is that headunit for computer was run over by a car.
