The family and memorializers of Boxcar Pinion are the source for those "Forever Bluegrass" bumper-stickers seen all over Chattanooga, and spotted sometimes all around the country. You can get a free one by mailing them, but it's much more fun by getting it as a bonus with your ticket to the annual Boxcar Pinion Memorial Bluegrass Festival. Put it on your calendar - May 4-6... Quite a treat for our little town.
