I bike in Toronto, but walk here in hilly hilly St. John's. About a mile each way to work, and a different mile each way to the grocery store. About four miles to the airport and three to the mall. I do wimp out and take the bus to Costco, though.
That said... walking is okay, especially when I can take "nature cuts" (like a shortcut, but through nature), but it's not fun and invigorating like biking.
