Boston Bib Number

I got my Boston race information packet today. I was relieved to find that my bib number is in the first 10000, so i get to go off in the first wave. This is the first year that Boston is instituting a two-wave start (one at noon, the second at 12:30) to alleviate the crowds in the neighborhoods of Hopkington where the race begins. I was resigned to being in the second wave, but i'm pretty happy to be in the first group. I know that it'll take a while to get across the start in any case-- so my gun time will be much slower than my net time-- but at least i won't be as impatient in the starting area.
