whatever the weather, just pretent it is exactically what you wanted to happen and nobody will know the difference.
The breakdows don't concern me as much, my stuff has been running for days as well but some of the electronics I use outside gets a little squirelly when wetIn the same boat with wind and weather. I am not worried about break downs, thing have been working well for days. On the Stressed out part.. Yeah I am there..
Tried the big party, invitation, RSVP etc a few years ago and I didn't have fun! To busy worring about who would show, where was the dang caterer, do we have enough or to much food etc..
This year I just told people we were having an open house Sat and Sun night.. stop by, have something to eat and drink. If we run out of food.. oh well first come First serve.. if no one shows up.. the homeless shelter will get hot roat beef for dinner Monday! I am going to try and enjoy myself this year and not worry about anything! Good luck with your event and try to chill out and have fun! You can't stop the wind and the weather man is almost always wrong!
