 They love this stuff, they eat poison ivy, they eat the porcelain berry, they eat the multi-flora rose, and that's what we're trying to get rid of. Just like the running of the bulls, we wanted to see them come out of the gate fast, which they did. They were a lot bigger than we thought, so that was really fun. And yeah, they just started working right away, so it's really fun to see wildlife like this in Riverside Park.
