From Camp Menotomy, way back in the time machine, going back to 1939, 1944, 1956 ......
https://www.lwhs.us/menotomy.htm .....when it looked like a happening summer camp.
I took a walk through the camp sometime about October 2012, before it got all posted 'no trespassing' as was a local practice back then and there were NO camper cabins, anywhere, and these non-existent cabins had no bunks and no bathrooms as they got replaced with tent platforms, or something(?).
Apparently, about 15-20 elevated tent platforms were there which had replaced the old cabins and there was nothing there in the way of electricity, plumbing, or indoor bathrooms ...... just tent platforms in groups of five in four different shoreline, forested locations.
No tennis courts, no indoor gym, no outdoor basketball court, no barn with horses, no coral, no pasture, no riding ring, no manicured and clipped green grass fields, no owners mansion cabin, no infirmary, no main lodge, no senior lodge, no junior lodge, no counselors shack, no cooks cabin, no library, no rainy day gymnastics cabin.
There was one grass all-purpose athletic field.
The one and only building which is there now is probably a dining room and kitchen with small living quarters, and two bathrooms as is shown in the Zillow listing.
The waterfront had a permanent dock which is still in place in the lake but there were no small boats like row boats, Sunfish or canoes, no water ski boat. No waterfront small buildings like for paddle and pfd storage or waterfront staff support.
It was mostly an untouched big pine trees and rocky shoreline Lake Winnipesaukee location that was very short on facilities and on campers, too, at least in 2012. Believe the last eight week Girl Scout full summer session was held in the year, 2000, 24-summers ago.
Maybe someone who attended the Camp Whispering Pines one week or two week sessions held there in the last twenty years in July and August can make a reply here.
