I started camping with my friends when I was in my teens. When we got motorbikes we had greater freedom to travel. Only needed basic equipment and 'wild camped' in secluded spots.
After meeting Dianne and graduating to a car (Moggie Minor), we used that to go camping, but would use B&B on occasions. When our son was born, we mainly used B&Bs, but the excuses people used to refuse accomodation to young families were flimsy in the extreme, so we turned to self catering.
After our daughters were born, we got our first camper van, and we've had one ever since. As for tent camping, this seems to be divided between those who use fairly basic kit (as camping used to be) and those who insist on a five star campsite with electric hookup for tents, 100% mobile phone coverage and of course a a TV cable so that they can watch their 40" plasma TV while "getting back to nature".
We're getting a bit soft now and camping (in all its forms) is not particularly cheap. We only use the motorhome in better weather (Mar - Nov) and over winter, we fly and stay in hotels.
