My husband had to go to San Francisco for a business trip recently, so James Wilson and I tagged along for a mini vacation. I was a little worried that I wouldn’t be able to exercise, but I quickly realized that just because I couldn’t go to a gym didn’t mean I couldn’t be active. Every day I loaded James Wilson into his stroller and set out on foot to see the sights. It was so much fun walking around the city, I barely noticed how far I was going. One day we went all the way from Union Square to the Ghirardelli chocolate factory (where, admittedly, we shared an ice cream sundae). Afterwards, we headed back to the hotel along the trolley route. As I pushed him up a hill, one went by and the driver offered to stop and pick us up (it was a pretty steep incline), but I said no. By the time we got back to the hotel, the muscles in my legs were tired, my pedometer counter read 17,000, and I knew I'd burned off that sundae—and then some.
