Need venue for fundraising dinner

I'm looking for a place to hold a fundraising dinner for our Light the Night team this summer. My preference would be to hold the event on a Saturday evening in August. If you know of a facility that we might be able to rent for the evening with little or not cost, please let me know via comments to this post or e-mail. We are open to different locations, but would hope that the size could accomodate 50-100 people for dinner and possibly a silent auction.

I'm also looking for volunteers to help -- food donations (I'm thinking a Spaghetti dinner could be delicious), setup crew, cleanup crew, donated auction items. If you have time to donate, that would also be much appreciated.

Thanks!

Mandy
