There's another way to approach this if you have an idea of what kinds of attractions you'd like to find. Delorme maps all work well with POI (point of interest) files from POIfactory.com. There are POI files for museums, amusments parks, etc, which you can load in an get an idea of what's available in your general area, and thereby fine-tune your routing.
So for me, I load in a POI layer for ski areas, along with another layer for micro breweries, followed by nearby pizza joints and of course nearby bank ATMs. And while attending the brewery I can load in a POI layer for state parks and hopefully find one within walking distance.
