Have a howling good time at the annual "Monsters on the Marsh" event at Marsh Haven Nature Center. This family-friendly event will be held rain or shine on Sunday, October 23 from 9 a.m. to 4 p.m. Come in costume for trick-or-treating, visit with the costumed critters, decorate Halloween cupcakes, make Halloween-themed crafts, go on a scavenger hunt, tour the museum displays and exhibits, and walk through the haunted woods, if you dare. For a small fee decorate a pumpkin to take home, fish for prizes at the fish pond, and have lunch in the snack area. The cost for admission to this special Monsters on the Marsh event is $3 for adults and $2 for children. Or join Marsh Haven Nature Center with a $20 family membership, which includes free admission for the rest of 2016 and all of the 2017 season. Visit www.marshhaven.com or call (920) 318-9518 for more information. Marsh Haven Nature Center is located at W10145 Highway 49, just three miles east of Waupun.
