Depending on what time of morning you’re up, you may want to watch or set your DVR to record “WCCO 4 News This Morning” at 5:45 a.m. Thursday. A camera crew is in Buffalo today filming the historic downtown area as part of WCCO’s ongoing “Saving Main Street” feature. If you miss it, www.minnesota.cbslocal.com posts segments of the series online after they air.
