over the summer i discovered millfoil thriving in my neighbor's pond. the pond is about 2 acres and by next summer the whole pond will be full of it. there is no way that i could have brought it in on my fishing gear. the boats are on the pond year round. how did it get there?

the owner doesn't care about what fish goes in the pond. i wanted to buy some catfish and bluegill but i need help finding a place that sells them.
