Adding to what Fred has said, I have been booked on several weddings where the B&G didn't have a clue as to where the reception was going to take place or who the Caterer was going to be as the DJ was the first thing they booked.
I have done many weddings here that the DJ budget was 80% of total wedding budget the $200 VFW fee was second! Many of the weddings done in this area the catering is done by the familes themselves the money is spent on entertainment. I find that the DJ budget is much higher for VFW hall weddings with the "poor folks" (common folks) than it is for upscale hotel ballroom and vineyard weddings!
Different people have different priorities! My preference is that I'd rather do the VFW style functions. Lots more fun!
