Oh Perna.....I hear what you are saying....been there done that.
I would say let it be....reschedule the appointment and give it no more thought. For some reason or another you are having an issue with it, whether it be the appointment itself or the weather or the combination of the two...who cares??? Why attempt something that may be dangerous if the weather turns bad?
Sit back, relax, stay with us here and go to another appointment
