Peer-to-peer camping

Is couchsurfing is too cushy for you, with all that central heating and indoor plumbing? Then check out SingleSpotCamping.com, a Swedish-based site that matches DIY travellers with the owners of backyards and garage entrances where wanderers can pitch their own tents. You still meet locals--you just don't have to sleep under their roof. For more, see this TreeHugger post.
