I've got a couple of old mesh hammocks that I've had since my teens and used to camp out in under an old army issue poncho (long before I discovered that there were other 'mad hammockers' out there). They're now relegated to use as gear hammocks or as a seat while day hiking.
For the past couple of years I've been using my DD Travel hammock and my sons have now joined in by buying themselves DD Scout hammocks (which I then made bug-nets for). My eldest son also won a hammock in DD Hammock's competition so now has this suspended in his bedroom and sleeps in it every night.
I can see our collection expanding though as my wife tried my hammock this year and despite her thinking it was silly, the moment she tried it I was instructed to go get her book & a glass of wine then leave her in peace. She's now determined to get one for herself...so at least I know what to get her for her birthday this year!
