This is an interesting idea, called campinmygarden.com it allows people to do just that. If you are happy to let people camp in your garden you can advertise on the website. garden owners charge around £10 a night for a pitch on their lawn. The website aims to provide more affordable accommodation for sports events, exhibitions and festivals in the UK although according to this article they are currently suffering from a distinct lack of gardens. It’s an interesting idea and as an experiment I typed in the Real Food Festival which I will be attending today. There appears to be 4 gardens available near by, should I feel like taking my tent with me, although personally I will commute back afterwards, preferring the comfort of my own bed.
