Lots of times. I used to like making things that most other campers didn't have like a 25 foot high Canadian flag pole, a fridge that kept things cool by evaporating water and a bath house made from a small tent and kids blow up pool (I had pipes running into it from the fire pit to heat the air and I would heat up the water I put into the pool. Cheers!
Many times over many years, starting with Scout camps and family holidays. The most recent was only about three weeks ago, meeting friends in the North of England for the first time since, well, guess!
