BYOB Wedding

I am helping to plan a halloween wedding for some close (but budget concerned) friends of mine and have hit a road block with the invites that I am doing from home. The bride would like the reception to be B.Y.O.B. There will be food and non-alcoholic beverages served, but she doesn`t want to have to supply all of our friends who would perfer spirits to food any day of the week, let alone on halloween.

We thought about doing a cash-bar but thought the idea of everyone bringing their favorite drink would be more cost effective on the guests, (because we all know times are tight) they wouldn`t have to pay for their drinks at $3.00+ a pop.

I was wondering what would be a better way to indicate this on the invitations??? B.Y.O.B. Reminds me too much of a frat party or something. I am leaning towards "light reception to follow..." but I am not sure if that will get the point across.

Any ideas would be greatly appreciated. Thanks
