The Bethel Board of Selectmen is set to present a budget to the Board of Finance tonight, with a 2.3 percent increase.  First Selectman Matt Knickerbocker called it a tight budget, and a work in progress.  There's a lot of uncertainty for municipalities this year because of the state threatening to reduce aid to schools by substantial amounts.  Knickerbocker says the state was pretty consistent for many years on road construction funding and school grants, but that's changed in the last 5 or 6 years.  Knickerbocker is also concerned about the state forcing municipalities to cover a state run program. He says that may violate the state constitution and prompt legal action.
