Back in the days when my children (now 49 and 47 years old) were toddlers I used to go deer and elk hunting in Colorado every year. Some trips we slept in the back of a station wagon, sometimes in a tent, once in the bed of a pickup truck with a tarp pulled over the top, always in below-freezing weather, and usually at or near 10,000 feet above sea level. One year I went by myself, sleeping in a GI-surplus "arctic" model sleeping bag laid out on an canvas tarp, which I then pulled over the top, with temps below zero, and woke up to find ice from my exhaled breath inside the tarp and sleeping bag and a foot of fresh snow overlying my accommodations.
Back in the day we looked forward to those trips and thought of it as having fun.
I clearly recall many nights with a full bladder demanding relief, but being unable to convince myself it was worth it to climb out of the sleeping bag to seek that relief while knowing that the bag would be ice cold before I could get back inside.
Some years later a half-dozen of us like-minded geniuses went together, pooled our funds, bought two GI-surplus "GP Small" tents, one for sleeping and one for cooking, eating, poker playing, beer drinking, and lie telling (first liar never stands a chance in elk camp). Each tent was equipped with a GI-surplus gasoline drip stove, inside temperatures always in the 50-60F range even when below zero outside in a blizzard. We thought we had it made, a week away from everyday concerns and nothing to worry about but getting far enough away from the tent while we performed our necessary bodily functions.
In much later years I had solar panels with 12V charge controllers and deep cycle batteries with 12VDC-120VAC inverter, LED lights, electric blankets, and a Mr. Coffee machine ready to go every morning.
None of that compared to the comfort of a 31-foot Aerolite camping trailer with forced air heat, air conditioning, self-contained bathroom facility, and full kitchen.
No more! My camping out days are long behind me. Gave away my tents, sleeping bags, cots, propane heater, camp stove, and everything else associated with those days. Wonderful memories, but I won't be adding any more similar experiences! Roughing it now means staying in a motel without WiFi or premium cable channels.
You can probably find me at the nearest Holiday Inn Express! Stop by for coffee in the morning if you like.
