I have to agree, a pot luck is a bad idea for a reception. You can keep it simple with that idea but provide the food and drink. We plan on having a backyard BBQ for our AHR because I really didn't want one and just want to keep it simple, and my mom, FMIL, sister and I are making all the food, and FI and his brothers are in charge of drinks. We're doing this in my parents backyard with a tent a few tables and chairs and setting up the sound system.
