The green line on the above map shows the most direct route from work to my house (well, toward my house - I needed to zoom in and the route is too long). There are scheduled times when the road on the green line is closed, in which case I take the orange route home. There are also scheduled times - maybe 2 or 3 per month that I have to deal with - when the orange route is also shut down. In these cases, I take the red route, which joins up with the other two just off the top of the image.
Last night, the green route was scheduled to be open, but due to some situation was closed. I made it about 1/2 mile before I had to turn around and head back. I called Scott to tell him I'd be a little bit late, and while I was talking to him, I wasn't paying attention to my surroundings and took the red route instead of the orange. And then 10 minutes later I must have REALLY not been paying attention because I made a wrong turn and couldn't make a U-turn for a mile after that! (demonstrated above my the blue squiggle)
I finally made it home, though I'm not sure how late I was. Probably 15-20 minutes. That's pretty significant considering the normal trip home only takes 25-30.
Tonight? I'll drive home with my phone in its holster.
