So I proceeded with opening the package.
What could it be? It was this:
When I ran Boston in 2010 I lamented the fact that I neglected to steal one of the 8 zillion "No Stopping Monday" signs that lined the course. My friend April, marathon cheerer-oner of the universe, happened to be in Boston when I ran and watched me slog on by a few times. Even better, she snagged a sign and sent it my way.
Sweet! I am thinking of whiting out "Boston" and "Monday" and writing in "Philadelphia" and "Sunday" and then making Bill wave it around the marathon course as he cheers his head off on Sunday.
