Each summer between 1972 and about 1986 our family holiday (vacation) was two weeks camping in France. Usually we would spend one week in each of two different campsites. These trips involved squeezing five people and all our stuff into a modest family car and a long drive interrupted by a ferry crossing. They did not involve putting up a tent because we used large multi-room pre-erected tents. We did however enjoy the rest of the camping experience including occasional severe weather.
So I knew it was possible.
Last night my family of five slept under canvas for the first time. We did fine.
Today has been a classic festival day. It included music, kids art, talks, cooking on a camp fire. It has been great. Hopefully we'll sleep again tonight. I'll post some pictures when I can.
