I’ve been looking for new ways to grow the readership of this blog. So I’ve decided to have a contest. Rather than make people pay for sponsorship, I’d like to do something that will get people more engaged in being a sponsor, without having to pay for it right away.

Many cities who use the Great Lakes for their drinking water source have been affected by the invasion of the zebra mussels. Read the rest of this entry →
