I was in a wanderin' mood this afternoon, so I took the bus out to Crissy Field and strolled around in the gorgeous sunshine for a bit. While I was there I took a look at the so-called Cool Globes that currently line the promenade near the water. Similar to those wretched hearts that were scattered around the city a year or so ago, artists have been invited to decorate large globes, in this case themed to solutions to the problem of global warming. The niftiest one I saw was done by Lindsay Obermeyer, who knitted her globe a cozy turtleneck using the same fiber that usually goes into making parachute cords. Other solutions included things like rooftop gardens and wind power, in other words nothing you haven't heard before. But the globes get points from me for effort, even if they are sponsored by a car company.
