Here's something that some of you (particularly iris123) may find interesting...
Board-track racing (huge steeply-banked ovals - and sometimes circles - constructed from wood) was huge in the US from 1910 until the 1920's, and is considered one of the forerunners of speedway on this side of the pond. The Playa del Rey track in California opened in 1910, and was followed by dozens of others around the country. In fact, we had a couple here in the Cincinnati area, with one in Sharonville (a couple of miles from where I work), and the Lagoon Raceway in over the river in Ludlow, Kentucky. The tracks soon became known as "Murderdromes" due to the amount of fatalities, which included several of the leading riders. Worse than that, a number of spectators were to lose their lives, with a major tragedy occurring at the Lagoon Raceway in July, 1913, when Odin Johnson was killed, along with seven spectators.
One of the biggest names in the sport was Eddie Brinck. Sadly, Brinck was to lose his life in August 1927, during a race in Springfield, Massachusetts. Last week, I finally got around to visiting the AMA Hall of Fame inductee's grave up in Dayton.
