I have two basic routes, but each of them have several variations, based on traffic, need to be somewhere at a specific time, desire for fresher air. etc. One route is 7 miles and on a MUP. The other is mainly on a sparsely-traffic'ed (well... sometimes...) 4-lane.
Right now I am mainly doing the 4-lane route, with a 2-mile side detour through several mall parking lots, an alley and a "corporate drive".
