Nothing finer than spending an afternoon relaxing in a hammock!
I own several hammocks, a Hennessy Asym Delux Explorer, DD Camping hammock and a custom clone of a Warbonnet as they weren't until recently available in the UK and I'm tempted to get the real thing soon anyway.
It'd be nice to use the garden as a space to use them on warm summer nights or to dry them after a wet weekend camping. The temporary solutions are fine, but I don't really have a place to store them and if I have to do any significant assembly, it'll probably never get used.
So I built a permanent solution using 4x4 and postcrete!
