Now, that's something I could get involved in...and I bet a lot of my truck-owning gun club buddies would, too!

The possibilities do seem endless. And the more absurd we can make it, the better.

Get Inga to serve as High Priestess, blessing each bag as it goes over the fence.

Get the Society for Creative Anchronism to bring a catapult. I'll show up in chain mail and emcee that part of the event.

Bring in the Junkyard Wars crowd -- "Given a standard junkyard, how far can you throw a 40-pound bag of trash?"

Hmmm...

An NRA sanctioned skeet shooting event. The bag full of trash is lofted via catapult and just before clearing the border fence it gets shredded by a load of 12-gauge shot, and spills all over the Mexican side and scatters in the wind.
