This year’s outing was held, Saturday, April 20, 2024.  Like last year, this is the latest date we’ve ever had this trip.  (AGAIN a good thing, as Marathon County’s April weather has felt more like February).  The weather was cold 30 degrees, very breezy and partly cloudy.  By the time we were done it was still only 35degrees. We had a total of 15 attendees from across... Read More
