Hanford Stake Father and Son/Aaronic Priesthood Commemoration

This friday the Hanford California stake will be doing their Aaronic Priesthood commemoration campout at the site of the Fresno California Temple.  I will be attempting to make contacts on the general portion of the 40 meter voice bands on Friday evening to see if I can make any contacts from the temple site.  I've google earthed the site and there appears to be some trees where I can string up my homebrew dipole.  Hopefully, if the set up allows this my plan will be able to go through for doing some work on the band.  I plan on making a special QSL card on the computer with the temple on it for any contacts made that evening.  Due to the large amount of foreign short wave stations and not knowing which ones I may recieve at this location, I have not picked out specific frequency.  Any suggestions?JasonKI6DKC
