Running Turmoil: What to Do?

It is lightly raining here. I have been patiently waiting for it to stop since 6:30 this morning, so that I can go for my run outside before spending the afternoon on a 4-hour flight. It doesn't look like it's raining that hard, but everyone out there on the street has an umbrella. So, I am in turmoil about what to do...I don't have a much left in my running window, from a packing/eating/airport commute/logistics standpoint. Do I go run in the rain? It's not lightening, so I think it's safe....but will I look like a Crazy Person (with capitals) here? (In Colorado, I wouldn't hesitate, there would be plenty of other nutso runners out there, too).

What to do?

And NO, treadmill is absolutely not an option.

UPDATE: I ran. And yes, I was the only nutso out there running. And yes, it was heavenly! As was the hot shower...and had I not been alone, I would most definitely have taken GQH's suggestion. (And yeeeesss, glaven I am well-aware that I could have still "indulged" solo but let's just not go there ok? ok.)
