Last Thursday, partway through my drive home on the final day of the expedition, I pulled into a highway rest stop and made a plate of lunch from the cooler. Pre-washed salad greens from the supermarket, pretty good pumpernickel bread, and and deli counter salads. Much easier to get vegetarian food from a good supermarket, if you can find one, than in a restaurant in an unknown town. If you're strictly vegan this won't work so well, but if you avoid eggs and dairy but don't throw a fit when they're present in the potato salad, you can get by.
So, chowing down, I looked up and saw this almost enchanted scene of goldenrod encroaching on the well-tended lawn. Weeds!
