In the rural, out of the way, off the beaten path, small village areas of New Hampshire, finding interesting, scenic things to photograph is not hard.
The hard part usually involves finding a decent place to park without causing a traffic hazard, looking out for ticks, looking out for loose dogs, deciding if you have time to stop, if it might be better to come back under better lighting conditions or if your car mates will tolerate another pull over.
New Hampshire is a target rich environment, especially if you get the less visited areas of the state, like along the Connecticut river, along the border with Vermont and in the Upper Valley region around Hanover and Dartmouth College, where the highways are wide open enough that they consistently catch out of state speeders doing 100+ because I guess they foolishly think there are no state troopers around.
I usually just point the car in a general directly, pick the secondary roads and get lost on purpose, hoping that the GPS will not take me down some crazy, dirt road mountain pass. Which has happened more than once.
Covered bridges found on maps are a good “destination” to find interesting things along the way – old vintage tractors (one of my favorite things to spot), vintage cars, beautiful old red barns, cows, waterfalls, rivers, etc. can all be found along the way. Drive slow, pull over and let people pass, turn off the radio and have the camera ready in the passenger seat. Pack a lunch, pack some drinks and use your emergency flashers as needed.
Bring your card if anyone asks what you are up to so you can show that you are not a Federal Agent, the tax inspector or game warden. Sometimes rural people get spooked when they see a strange car especially if it is out of state.
