Well I started with a sleeping bag and a tarp and a billy,( young and silly ) then progressed to a 3 man tent with a fly and a -10 sleeping bag ( a bit older then ) Woke up 1 day at "The Blue Duck " and I thought that I had wet myself during the night, the sleeping bag was sopping wet, turned out the temp got down to -6 at 10pm and the moisture in my breathe condensed over the top of the sleeping bag ( I've crossed that off of my things to do again ) So now I have a nice little 16 foot fully insulated caravan with a diesel heater in it, now that thing is magic , running on low setting it uses about .25 of a litre an hour and you're sitting inside toasty warm in a t shirt , oh yes, you do get smarter as you get older ( sometimes)
