I keep seeing a woman riding a bicycle while I'm driving my school bus around. She appears to be about the same age as me, maybe a little younger, and about in the same level of fitness as I am, from my observations of her riding. The other day I saw her taking her bike into the house after a ride, and prior to that I did not know where she lives. I would like to introduce myself to her and find out if she would like an occasional riding partner because my husband is not available sometimes. I don't want to appear to be a stalker, but I don't know any other way to do this other than going to her house and knocking on her door, which I am nervous about doing. Any suggestions?
