Oh. I see we have "umbrella user intolerance" (UUI) on this website. Oh yes, I've suffered the cruel jokes. Even from my hiking buddies. The "Mary Poppins" jokes. The "pretty parasol" jokes. The "i thought you had a satellite dish" jokes. Ahhhh yes.
I hike mostly desert. It can be 110 deg. on the desert floor, sun beating down...me standing cool and comfortable under my 100% portable shade (that doubles as a tarp pole)...the jokesters sunburned, sweat dripping, overheated...and still they make their insensitive jokes. The joke's on whom, here? I'll continue with my umbrella lifestyle, and no, I will not share my shade. Laugh all you want.
