Outside? In THIS weather??

Okay, so my 11 yr old is getting his Arrow of Light award in Scouts tomorrow night. Finally have all the tasks done. I've been telling the grandparents for two weeks now what building it will be in. And THIS AFTERNOON I get a message on my answering machine telling me that the pack meeting will be at the leaders house, in the backyard, not in the churchbuilding. Its been 39 degrees and VERY windy here for three days straight. Its a bring your own chair, wear a coat, lets sit around a campfire thing. Hello? Its almost November for petes sake and FREEZING! And now the grandparents cant come because of health issues. The one grandma had throat surgery Monday morning and cant sit by a smokey campfire, much less out in the cold. And the other just got out of the hospital with a leg puncture that required 30 some stitches because her skin is very paper thin. And that one also has diverticulitis(sp?) and has had both knees redone and has back problems. And I REFUSE to ask her to sit outside in 30 degree wether sucking down smoke fumes. And the leader could only say sorry. I dont want to hear sorry, I want you to move it back indoors so family can be in attendance! She's only having it in her backyard for her own convenience.
