Husbands Party
I agree with several posters to inquire about rental spaces. Here we have library, legion, church, community center, banks, senior center, and more that rent for reasonable costs. As to food, a potluck with friends is fun and perhaps you could supply the drinks and paper plates or whatever. If you like some entertainment scour your library or go on line for birthday poems, have the grand kids sing together, offer story-telling time to old friends, display old photographs and college yearbooks, play background music or feature the school choir or band, old songs bring back plenty of memories and if you are daring have a karaoke. To surprise him takes planning. Perhaps get someone to offer him a day out and drive him somewhere then to the designated place when the guest are all assembled. Say in lieu of gifts you want your guests to have fun!
