Welcome to Berks.... Turkey unfortunately have become quite scarce(and Deer on public lands on the 5c portion) around here over the last 10 years or so. Wieser SF, 110 + 106 are still probably your best areas for finding birds. I took a few off of 280 as well, but for some reason the PGC timbered several roosting areas over there destroying a couple of my "hotspots". It also gets tons of pressure since it is close to work for lots of people. You also have to deal with lots of "others"(joggers, walkers, bikers and horse riders) over there.
