I have not fished that area but I am a little familiar with it, my waist line was a recent victim of Shady Maple.
. Speedwell is probably the most talked or written about lake I've seen mentioned so maybe put that on your radar. Conestoga is a stream or small river that I have been over MANY times but have not fished it. It does look bassy to me and I believe it is also stocked with trout.
There would be no shame in shelving fishing for your trip, there is plenty to be enjoyed in the region and to gain some points with the wife.
. I know this because my wife drags me out there often! We like to visit the furniture stores, Shady Maple, Kings (has a trout hatchery too), Kitchen Kettle Village, Amish Farm and she even dragged me up to the Wolf Sanctuary near Speedwell a few years ago. It is a nice place to visit.
