I sent a LOR, 5x7 photo, and SASE to Ruth Eckerd Hall in Clearwater, Florida on July 24th and received a reply today, August 5th for a total of 12 days. The concert was on July 31st, so the address is obviously no longer valid. However, Ruth Eckerd Hall IS on the list of venues known to pass on mail (which they obviously did).
I live in Washington State, which is on the complete opposite side of the country, so it was pretty quick to arrive considering it was postmarked on the 1st (which was Saturday). I'm very pleased with the success, not only because Counting Crows is one of my all-time favorite bands, but also because the whole band signed it (which is awesome considering there are seven of them)!
