This is a tourist attraction and an asset to the fingerlakes.
People come to the Finger Lakes to go to a drive-in movie? If they do, what is the net gain to the Finger Lakes region, as a whole?

Why would you think that? Is the business you are advocating for contributing to those other businesses? If not, why not, under the principle, which you seem to subscribe to, that businesses should give money to other businesses? Have you donated to the drive-in? Do you habitually donate to businesses, to fund upgrades needed to increase their profits, or to keep them in business, if they're not getting enough customers to provide those funds? I'm sure many of them would appreciate the extra cash, because being in business isn't easy.
It shouldn't be hard to find businesses that need your help, if you'd just stop and ask them...after all, 8 out of 10 new businesses fail. With just a little help from you, maybe that wouldn't happen. Good luck, and remember...they're counting on you!
