I have another take on practising for camping
Scenario : NorthWest Festival is in town. Great bands, not really suitable for kids. Arrange for friends to have the kids for the night. Festival is walking distance from home. Have a great night, get drunk as 10 men.
wandering (stumbling) home after the event.
SWMBO : Do you have the keys ?
Me : no they're in your bag
SWMBO : But I downsized it and left it at friends.
me : [thinking fark, this isn't flash]
me : Don't worry, the camper has everything already in it.
Get home, remove cover, pop open and we're camping.
SMS friends next morning to bring keys around to get into house.
That's camping
