Sorry I'm coming in late on this - have been traveling the last couple
weeks. I'm aiming to have the Grand Canyon Star party the 21-28th
of June. There are inevitable complaints from many folks that their kids
are still in school early June, and yes, we do run the risk of monsoon
moisture late in the month, but the later dates gets the milky way up
sooner and Mars, getting near opposition, will also rise earlier.
I don't think we've ever gone later than the 24th, but think we should
try it.
