Interesting places I have slept

In a sleeping bag on a mattress on the floor of a squatted social centre in London
On the floor of a different squatted social centre in London
In a caravan in a protest camp
In a treehouse in a different protest camp
In a tent in multiple other protest camps
On the steps of a building I would (many years later) occaisionally work in
On a plane
On multiple overnight coaches across Europe

My current Sleep System whilst unconventional is a lot less interesting than these
