[PPRAANet] Date conflicts for Hamfest 2009?

[Rob Roller N7LV]

I'm in the process of scheduling the 2009 PPRAA Swapfest for a Saturday in 
July.  Other than July 4 (which we will not use for our hamfest), we have 
July 11, 18, and 25.

Does anyone know of any conflicts with any of those dates with any other 
amateur radio events going on?

I've looked at a few things, like some public service events:

PPIHC is July 19.

Triple Crown of Running, Summer Roundup is July 5.

MS-150 is June 28/29 (sometimes this is in July).

MARC VE test session is July 11.

I'm not sending in the request form for a few more days.  I'll be looking 
for other potential conflicts based on past years activities.  I'd 
appreciate any help in identifying other events that could help select the 
best, or least objectionable, date.

Thanks
