I have had a couple of nights out in Edinburgh without any bother. I was planning a long distance walk and without suitable trees in my garden wanted to try things out. My first overnight was near the Edinburgh zoo but being up a hill near a busy road was quite noisy. Not realising a mummy bag alone would not work at about 4C I had a bit of CBS. So a bit of reading of this forum and a bit of a look at Shug's videos and I added an inflatable 3/4 sleepmat and some reflective windscreen material and went back out to a local golf course in the middle of the City which was much quieter. That was much better but sill a little cold at times so I chopped up and old synthetic summer sleeping bag and made an under quilt for the actual walk which worked pretty well. I have put a report on here http://www.walkhighlands.co.uk/Forum...p?f=25&t=26347
It will probably be spring before I am out again, unless a down underquilt arrives for Christmas which will require another urban outing.
