She'll probably need to go at least 3 times before it's worth it. If it's that far it's a harder call IMO. Ellen-only day tix can be had for cheap sometimes, especially weekdays
Turners Falls airport is a good spot. Or on the top of Mt Sugarloaf (which you can drive up), except you aren't in position to move easily. Fields between North Amherst and North Hadley too, wide open fields over there.
