For pure genealogy purposes, there are a couple out of the way places I would like to see. I have not made it, but my brother came back from New Jersey a couple weeks ago, and he stopped in Kentucky to see Argabright (my maiden name) Hollow, which is over by Lodiberg (sp?). Really pretty backwoods valley where our ancestors settled in the 1820's. There is also an Argabright Fort around there somewhere. On my husband's side of the family, we want to make a trip to Idaho to check out Schweitzer Valley. Seems like our ancestors sure liked to live in out of the way places.
Speaking of New Jersey, there is a great museum in Monroe, NJ. It is a geology and natural history museum, showcasing practical masonry with full size displays of stone products used in various building and landscaping projects. There is also a man-made lake with a gazebo jutting out over the lake. My brother married his wife there back in 2004.
