Got some supplies from Ron Sitko, said hello to forum member "gemering", and found some bits and pieces here and there, and (sigh) more records.
One vendor was offering 50 records for $10 ( around mid-day), including diamond discs. Another chap was already digging, and I decided to let him hunt in peace. He wound-up taking away 200 DD's
I found my 50 later, including about 12 DD's that I thought were worth a try at the price... I left behind a Homer Rodeheaver DD that looked un-played.
I also found about 12 cylinders that met my interests and budget.
An accidental sight was also most encouraging: a male teenager, accompanied presumably by his mother, walking out with a load of 10-inch 78's under his arm.
Always a good day at Wayne, followed by a stop at Hot Dog Johnny on the way home !
