The one note I have is that some of the rumors I have heard were true and others were not in regards to this team…that is why I wait to publish things until I am 100% sure.

I am excited to see how the County Executive and his team works going forward. Hopefully I can build good relationships with them all in order to get an occasional quote or two for articles on the blog.
