I used to for a few years drive between Bloomington and Greencastle Indiana three days a week. Amazing carnage on those two-laned highways. I narrowly missed deer in my ancient Honda Accord on several occasions. I think that there is so much wooded area in NH that animals don’t need to cross roads as much—anyway, I travel a lot here too but rarely see road kill like I did in the midwest where it’s mostly farmland. (Actually witness the death of a deer and a Cadillac when cycling with a group one morning; we spooked the deer that was feeding adjacent to the interstate. The deer ran as we passed over the highway and went into the road just in time for us to see it collide with a new-model Cadillac—just destroyed the front end and the deer of course was just a bag of bones and meat in the aftermath.)
