Thanks for all the responses. One thing I forgot to mention: my wife and I are new to this area, and we found an apartment soon after arriving. Actually, the apartment has worked out well, but maybe we'd choose a different location now.
I appreciate what people are saying about motivation to ride. I certainly could extend my commute, but my personality is such that not having a choice would work better. I do ride on the weekends, but I like the idea of making biking a lifestyle more than recreation.
Give it some more thought...
