The white vehicle I posted yesterday appears to be 1965-1968 Ford Galaxie 500 XL. It’s unclear when it was ditched in the woods, yet let’s assume mid sixties to early/mid 70s. That’s ten or so years of car ditching opportunity. The 69 Oldsmobile borrowed by Eddy was ditched in July 1977. So if someone were to ditch a vehicle in that area they’d need to have some knowledge of the geography, favorable weather conditions, and precise knowledge of the off-the-beaten-path location of the final destination. Most of the trails in that area (present day) are compact soil and peat gravel. If you have an especially wet season you would conceivably get stuck very easily. It looks like prime times for dry trails were 1963-1969, 1971, 1975, and a small sliver of 1977 based on drought conditions in NH. Neither an Oldsmobile nor Galaxie are off-road vehicles. They’re low to the ground and heavy (a Galaxie is 3500-3700lbs). Most of the terrain is downhill, yet the initial sections and between miles 1 and 2, you’d have to climb. Another observation (from current day) is that people do visit this area. I found a red solo cup and empty bottle of wine in the vicinity of the Galaxie. Perhaps this may have been a well known spot in 60s and 70s too among those who partake in libations in the woods.
