What region are you in? I take the family to Union Pier every summer and I’m praying we are able to do it this year. It’s the happiest time of year for me. The SW side of the lake in MI is absolutely the best side imho. Although you can make a very good argument for Traverse City and the UP too.From talking to postal employees in Western Michigan I gather the Detroit processing center is very short staffed right now, resulting in delays for mail coming into, or out of, the state.
