OPT outside should be more than just on Black Friday, don't you agree? Or maybe you just need to burn some holiday calories. Bring the whole family, in-laws and all as we hike the trails at Annett Nature Center. There will be light snacks and time after the hike to explore the educational exhibits. Registration is required by November 29, 2019. Visit warrenccb.org or call 515-961-6169 to reserve your spot.
