I've been wheeling since my second year of college (1987), and this is the only time that's ever happened - 75% of the time, you have to shoo the people off so you can get work done because they really want to help. 24% of the time, you have helpers, and the 1% of the time (until today) you'd get the people coming up to talk and you'd learn it was their first outting (of that group, most end up wheeling with us) - thus, this was flat out amazing to me.... maybe he thought he knew me (it is kind of a common greeting among my friends)
