Holly, MI — A hotel was among several businesses damaged as a fire swept through part of the downtown of a northern Oakland County village. Dozens of firefighters from area departments battled the blaze which started about 4 p.m. Tuesday in Holly, about 53 miles northwest of Detroit. About a half-dozen people, including five firefighters, required medical treatment due to the heat from the flames and hot weather as temperatures Tuesday topped 90 degrees. The fire appears to have started near a building that housed an antiques and collectibles shop. Jon Ruthenbeck, a member of the Oakland County Incident Management Team, told The Detroit News that about a half-dozen structures suffered flame or smoke damage.
