In reply to icehockeyhair: Great thread - have been mulling similar idea sometime soon - in similar area.... look forward to some informed replys!
I was thinking about Yellowcraigs and finding a reasonably discreet spot somewhere but I have no idea how leery it may get at night on a nice summers day. The challenge on this sort of thing is finidng a nice spot thats accessible but doesn't run risk of becoming a party zone for local neds or right next to teh local dogging spot. Middle of noweher I wild camp without a hesitation, anywhere near civilisation the nerve levels begin to rise for me....
I also wondered about Pentlands... walk up from Bonaly and find a spot perhaps?
