and actually, this one we just added to extreme cleanup. it's our newest one. there's 60-some in here, all sorts of different crazy messages, really cool. this is my ultimate one, called lavender for you. it's written for guitar. so somebody was a musician. this one they put the postage money in there to send it back. so i probably need to do that. this one, this one was from a long time ago. 1993. the flood of 1993. they're smart enough to put rocks in it so it weights it down so the current takes it. here's one. this one's pretty cool. bill clinton, picture of bill clinton. it's kind of cool to find it. >> the work is uniquely rewarding but holding cleanups in town after town is challenging. >> we're moving and setting up cleanups and making it happen. it's always go, go, go. it's kind of like being in a band. bands have tour buses. we have a barge.
