Okay, you really haven't said where you are, but 56 miles is a pretty long stretch for Montgomery Co. When I lived on the West Side of Houston, call it the Dairy Ashford/I-10 area, I could not pick them up. When I was mobile (on the way to Houston Amateur Radio) I could start to get them as I was getting off of the Beltway on I-45, lost them and would get them again up the road.
Now for your particular problem, a good beam pointing at one of the sites might work provided you were using good (I mean really good, like hardline) feedline. Montomery Co. is not very strong, all the repeaters are limited to 100 watts and it seems the max ERP is under 170 watts and probably the antennas are all focused into the county so you being 56 miles away, you are really trying to stretch it.
