Yeah, been there done that with quite a few large collections. One I remember was around this time of year and it was hot like it's been this year, 90 with high humidity and this guy wants me to check out his records in this utility shack. The front half was filled with lawn mowers and yard care tools, etc. and the back half was filled with vinyl in boxes on the floor and up on shelves and table. I swear I lost 5 or 10 lbs. in sweat and needed a good hot shower when I was done. Most of the stuff was rough to OK but it was worth looking at as there was early Rock stuff...Little Richard,Buddy,Ricky,Fats,Valens,Everly Bros.,Rockabilly,etc. (but no Gene Vincent) that a relative in the Army brought home from Germany and UK. The very last LP I pulled from the last stack was a British Buddy Holly so it ended on a good note. He wanted me to take them all for a good price but I declined. At least he wasn't an all or nothing type so I bought around 100 LP's and I was so hot and tired that I couldn't look thru the huge totes of 45's so I asked if I could come back. I called a few weeks later and a real estate sale sign was in the yard and I peeked in the shed and it was totally empty so who knows where the 45's ended up. I was kinda anti 45 at the time but now I wished I would have bit the bullet and rooted around.
