AS many have said, if it's not going to be cold, OK. And if footing is not going to be much of an issue, OK. I find that taking down the tent in the rain is worse than putting it up, though I don't like either.
I have pretty good rain gear and like the feeling of being properly dressed (hmm, I should give that a try at work and around town, eh?) and comfortable in an otherwise uncomfortable environment. I get a good feeling about it that I don't quite understand.
But it's still hard first starting out in the rain, and maybe harder still deciding to do so when there are alternatives. Once I get moving and am warm, and if the glasses don't fog up, it's pleasant.
