Re: [96attendees] T-Shirts

[Ted Lemon <[e-mail]>]

BTW, one thing about T-shirt sizes here is that apparently german T-shirt
sizes are different than U.S. sizes.   This isn't unusual, but usually is
in the other direction.   So I said I was a men's large, but they gave me a
men's medium, which would be very tight on me if it were a U.S. shirt.
This may be why there weren't enough of the small shirts.

This is kind of hard to plan for.
