Bill is correct on the annual shoot. See Events tab on Ernie's website which is here:

In the past it's been 100 birds each at Hidden Hollow and at Rock Mountain Sporting Clays, both in northeastern PA. Rock Mtn. is hosting this year's PA SC Championship held over 4 days in July. (The Side by Side combo shoot is August 18 & 19. Or, I should say the 18th OR the 19th.) You can shoot both courses in one day and in fact, that's what many shooters do. The two clubs are about 20 minutes or so apart. Mike, who along with his wife Susan are owners of Rock Mtn, is a SxS shooter himself and he sets great targets. I hope this is helpful. Frank

A wonderful day or days out with the SxS's and our friends. What could be nicer? Frank
