[Geysers] Vixen Geyser: pre and post shutdown

[william barger]

Will, Polly, and I watched Vixen for an hour (stopping many visitors so that 
they could watch the next eruption).  We had a lot of fun watching the 
eruptions and then waited expectantly with breathes held to listen to the 
drain.  What fun!  Hope to see some gazers this weekend.  Kitt Barger
