We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
We are on, regardless of weather. There is always a rainbow somewhere, and human skin is waterproof.
Rain gear advised, especially in the morning. Our team hated the idea of canceling an 11-mile hike because of some dumb rainstorms...especially the gals.
Rightly so. Maggie's people ain't askeered of weather. My sister's motto: "There is no bad weather, only bad gear."
My motto: "Any morning I awake healthy and alive is gonna be the best day in my life." Then I go to the gym whether I believe my motto or not. If my workout doesn't kill me (I do my best to kill myself in it), I figger I am probably good for another 24 hrs. That is comforting.
My suggestion would be to not cancel under any circumstances.
If it's pouring down rain, meet up and find a venue where you can all sit and have a drink and/or something to eat. Everyone could leave in their own time but at least the camaraderie could be briefly enjoyed.
I would think the hike is more about meeting Maggie's readers than seeing the sights.
You guys might be able to come up with a Plan B. Museums and such that can be viewed out of the rain. Might mean an Uber caravan to get everyone there and I concede that woudn't be optimum, but it would be something.
