That's a tough one. The only thing I can suggest, is for the two of you to sit down and figure out, who is more financially able to travel for the wedding ~ his parents or yours? If you have the wedding in PA then both families would have to travel, making it most fair to all. The only other thing I can think of is to have two small ceremonies, one in his home town and one in yours. Or maybe just have the parents come to PA for the actual wedding vows, then have a small party celebration in each home town.
