I went out with an empty Honda Element hoping to buy room full of 45s 78s and LPs, but unfortunately there wasn't enough good stuff to make it worth buying, so I had to leave it. After that I decided not to waste the day and went looking in thrift stores, antique stores, and at garage sales to see if there were any good vinyl records to buy. There were. I bought some RCA Victor records without the dog logo, some Sun records and other rare records.
