Today I walked around the bus yard 2 times before I went home. Took me 22 min. It's a big place with over 100 buses and parking for about 150 people plus all the administrative offices and of course the 6 bay garage and 2 bay body shop. But it was cooler at 8:30 than it would have been at 10.
Also, I've started parking my car farther away from the door I go in to sign up for my work, at least in the morning. In the afternoon I park where I can find a spot. Either way, I'm getting in more walking than just my "dedicated" time.
Way to go Angela on walking up 4 flights. I get winded just thinking about it!
