As the concert continued, and the sun set, state police and Otsego County deputies, who had been covering the perimeters, were arriving to assist with crowd dispersal.
But up to that point, smiles and friendly crowds had been the tone of the day, said Covert, who said he has been to three Grateful Dead concerts. At 9:30 p.m., a man at a local restaurant stood in the doorway and said police had made an arrest for drugs. Covert said state police did make an arrest during the event, but no details were available. Medical crews responded to a few calls, but no major injuries or incidents were reported.
‘‘The people are beautiful — the vibe is very friendly,’’ said Karen Katz, wife of the Cooperstown mayor, who said she had taken advantage of the opportunity to buy clothes not usually found for sale in the village, including a skirt made of recycled neckties.
Another business owner, who requested anonymity, objected to some of the access granted to Shakedown Street vendors.
John, a vendor who gave his first name only, said he had been to many venues during 15 years on Shakedown Street and liked being in Cooperstown. Two officers walked by doing their job and smiling, and John said that was a welcome sign.
