After reading the threads concering hammocks & group buys, I figure a lot of folk here must use hammocks! There's some pretty cheap ones for sale on evil bay at the minute, starting bid £19.99 & I've been contemplating asking my wife, mother-in-law, anyone, for one for Christmas. Seems like it beats laying down on the ground, but I get the sneaky suspiscion that cold air is going to circulate & freeze the proverbials! Is this a correct assumption, or would a decent sleeping bag cut out the cold air below, above & all around?! Any advice will be greatly received! Thanks all
