I’ll just bet that milfoil they found in Norwood Pond (Sept. 5 – 11) came of those snowmobiles they race and sink out there. I’ll bet that because they are not a normal watercraft nobody checks them for, or even considers them to be a carrier of, an invasive species like milfoil, or even worse. They have apparently been running those things on different bodies of water, which very likely hold milfoil spores that could have been introduced into or pond. I’ll bet nobody even considered them.
