What do you get when you put a hundred thousand football fans in one spot? Lots of trash.

But these people are trying to change that. They’ve joined a growing movement across the country. They’re hosting a green tailgate. They’ve given some thought to the environmental impact of their party.

Carpooling is the first step to a green tailgate. You use less gas and you save money on parking.

What you bring to the tailgate can make a big difference. If you choose to drink beer, support a local brewery and take along some re-usable growlers.

“It’s a lot less recyclables things of that nature, good beer too. Any good tailgate is complete with good beer," State College student, Andy Martin says.

If you prefer bottled beer, you can find organic that tastes great. And the lack of chemicals is better for the environment.

The same can be said for your burgers and hot dogs. Try a portabella mushroom burger or a veggie dog.

And cook on propane, it burns cleaner than charcoal and leaves behind less waste. What you eat on and with, can be green too. Use items you can take home, wash, and use again.

"I think it's a great idea, I’m very willing to do the silverware, bring the plates to help eliminate the waste that we bring here to the university, very willing to do that," Thad Will says.

And don't forget the same rules for your back yard barbeque.

"We didn't use any plastic, we recycled everything. Easy to do at home, just as easy to do at the stadium," Will adds.

If you do have bottles and cans, make sure you recycle. Bring an extra bag for these items and make sure they end up in the right place.

These green tailgaters think the idea is spreading across the country and scoring big for the environment.

"I think its consciousness, if people are just aware and conscious of it, that's where the contagiousness comes and it just brings everyone together if everyone just pitches in and does their part," Bond Reinhardt says.

A crank radio is another good idea for a tailgate. You can catch the pre-game show without using any electricity or batteries.
