O' technique on my way to work?

I ride my bike to work most days and I pass through three orienteering maps. It seems like I ought to be able to come up with a way to get some O' technique training on my commute.One possibility is to draw a few control circles on the map - along the route but not necessarily on the route - and catch a glimpse of each location as I pass. I could see how soon I could spot each control location.
