It's odd how the wrong route to the right place (or places in this case) can have a profound effect on my efficiency and state of mind. Recently, I spent a day crisscrossing Brownsville while visiting and photographing different properties. About the fourth time I found myself backtracking my route in heavy traffic, I became irritated that I hadn't planned my outing better.
Over the years, I've considered using some of the paid services for route optimization. I never could quite justify a monthly subscription for something I don't use regularly.
I found OptiMap today, and it works great. I tried it out on the iPad; my list of twenty different addresses was routed to show the fastest round trip.
I'm a fan, and am going send these folks some money to encourage future development and continued support of this service.
