Hi girls! I have yet another freak out. We're havning C&R outside at a friend's house October 23rd. Aproximately 160-175 guests with 23 60" round tables. My concern is that I have no rain plan. I just checked with our rental place and it's going to cost $1,000 for a tent that would be big enough to fit everyone and I still wouldn't have enough room to have the ceremony away from the tables! Should I really be this concerned about it raining? All the stuff online says the avg precipitation in Oct. is .6 inches.
