With the calendar now reading October, it’s only natural to start thinking about bright fall colors taking over our scenic landscape. While it’s still a little early for the peak foliage to be around us, you can capture plenty of it in the work of Byron Carr. Carr’s show, appropriately entitled Autumnal, is currently hanging in the Kimball-Jenkins Estate mansion through the end of October, with an artist reception on Thursday from 5 to 7 p.m.
