I haven't read it anywhere well known, but much of my very first reading was carried out while I was sitting beneath stacks of old school chairs with canvas seats. I found a very good hiding place where these had been stored in an old cloak room, and by crawling beneath them I came to a clearing where the light shone through a window and all was silent, so much so that I ended up late for a fair few lessons.
I have also read Tolkien in various sheds, including a poultry shed, in a van and while sitting with my feet in a river.
