do bats hibernate? - Google Search http://bit.ly/1ugNJrc
Bat hibernation probably explains why I have not recently been chased by hungry bats. Late in the season, fitness buffs must look awfully tasty to cold bats. When you are radiating alot of heat, you look more attractive to bats and mosquitoes as well. This is one reason I prefer biking. Angry dive bombing birds usually miss the bicyclers too. Bees and wasps provide alot of incentive to improve your uphill skills. Bicyclers also seem to have an advantage against rock-throwing citizens, tho I'd imagine the runners do OK. As a matter of fact, Baltimore is not a castle doctrine state, and running appears to be a Baltimore City tradition. So, I thought that I would improve my running skills. You should see the little vandals scamper.
