I drive a truck, I would throw the bike in the back and escort the young lady home.
On a somewhat similiar thought. I work out at lunch most days. I use the stairmaster that is placed on a platform above and behind the treadmills. For most of this summer we have had two ladies who could be this young ladies twin run on the treadmills. Most times the 4 stairmasters are empty. Whenever the two with the short see through shorts are there, the place is full. It makes the 10 to 15 minutes they are there go by very quickly.
