So, another update.. rapidly closing on 4 years sleeping outside and I'm surviving the biggest storms for 7 years in Ciara. 70mph+ winds have made sleeping outside like being on the back of a flat-bed wagon driving down the motorway in the fast lane.
My current tent set up is a 4-man tent, with a smaller 3 man tent fitting inside! Double layering has keep the rain out over the past year, anything that gets through the outer tent, still has to penetrate the inner waterproof layer.
I've used extra guy lines tied to a couple of trees and fence posts to fend off the wind and whilst it's been bloody flappy at night, I've still slept OK with my ear plugs in.
April will be 4 years since I've slept in the house and I'm still loving it.
