A lot of us take pictures of the Ohio River -- bridges, wildlife, sunsets and boats. Barry Griffith does, too, but he does something a bit more labor intensive, too. He does some good line drawings of towboats, as you can see in this example.
As far as I know, he's one of the few people who do such drawings of towboats -- a relatively unknown part of the transportation system here in the middle of the country.
This is not a paid ad, and I don't get a cut of anything Barry sells. But he has been pretty good to me and Adam through our Internet-based acquaintance of three years or more, and his art is good stuff. It's worth a look.
