X - Sherri Cassara Designs: Newland Barn Wedding. This might be a good idea. Get some cheap blankets in the early spring. I don't think it'll get that cold at night but I want people to be comfortable.
Lawn games like croquet, bocce ball, beanbag toss and horseshoes are simple to set up and easy for kids and adults to play during cocktail hour and after dinner. Not a bad idea when there's a gap between wedding & reception. This might be kinda fun.
