I remember when Chris and I would run into rain while backpacking. It was rarely a big deal -- mainly just an excuse to sit back and read or sip hot tea in the tent or, you now, be lazy in other ways. :)
It's a whole 'nother deal with two rambunctious kiddos, though. We were relieved when the Gilles crew showed up and the rain stopped! But meanwhile, Chris and the kiddos made the best of kayaking in the rain and knocking around camp in full Helly Hansen attire.
