Plans that involve the outdoors rarely involve only two days notice for me - plans are either spontaneous or in more than a week. Then again, my plans rarely involve the outdoors.
> UV index to decide if I need sunscreen
My skin tone is known as "fish belly", so I always need sunblock, but unless I'm planning to be outside at length (which I largely dont do) I dont really do so.
> decide what to wear in the morning
I may be odd, but my day to day wear doesn't really vary other than by season. When I lived in Pennsylvania and Virginia the weather changed dramatically enough over the day that dressing lighter or warmer was an invitation for problems. Now that I'm in Seattle, the weather is fairly consistent over the day, but I've never found myself wishing I had known the forecast when I dressed.
> I don't use umbrella's
Mostly the same, particularly here in Seattle. Before, if it was raining hard the need was obvious, and if it wasn't I didn't want to carry around something is just lose before I needed it.
I'm not trying to poop on your feedback (really!), it's just these are largely the arguments I've heard that dont seem to apply to me. Do people really spend that much more time outside than I do? Am I some sort of sky-avoiding freak?
