PITTSFIELD â The week begins with a lull in activity as the Bay State marks Patriotâs Day, but revs up quickly as officials knock down city business in advance budget hearings on the fast approach. On Tuesday, the Police Advisory and Review Board meets to handle regular case reviews, and discuss new policy review language with Police Chief Michael Wynn, not long after his appointment to the statewide commission tasked with developing a professional police certification system for officers. And on the recreation front, opposition is growing against the mountain bike skills course the Parks Commission supports building in Springside Park, which is being spearheaded by Alison McGee, the city School Committee member and New England Mountain Bike Association Berkshire chapter president.
