Ok, so if you want to play a little bit extra indoors, you need to talk
to Mike Mattingly at Vetta by email:

mmattingly@...

Tell him what time you'd like to play and that you're with the Wash U
club and he'll write you down on the court sheet. The rate will be
$15/court/hour unless it's during peak hours (~6 p.m.), then it will be
something like $25.
