Sure, sometimes it's more convenient to work at staying dry...especially if you need to be dry for a reason--work, an appointment, grocery shopping, etc...I'm pointing out and advocating something different...

Getting wet or cold; neither "causes" sickness...that theory was debunked years ago...

I commute to work in cities for some of my gigs, but don't live in them...my leisure time is mine...getting wet..?...It's just not that big of a deal when I have no pressing business...fear of getting wet is no reason to miss the magic of standing out in the rain...

We lead different lives, my friend...and both are OK...
