“Happy Accidents: An Exhibit of Bob Ross Paintings”

Ross’s long-running painting-instruction program ended when he died in 1995, but new generations of relaxation seekers have discovered his nap-inducing (in a good way!) PBS show via online streaming. Happy little trees will abound at this exhibit in Purcellville of 28 of Ross’s signature soothing nature scenes—one of the largest-ever showings of his work.
