Space travel was not a problem for Captain Kirk, but a light-Labor Day rain kept William Shatner from a motorcycle ride around Seneca Lake. Shanter, his wife Elizabeth, and Chicago D.J. Mancow Muller were to lead the charity ride around Seneca Lake which was to include a stop at the Geneva Chamber of Commerce.The group never made it to Geneva to the disappointment of about a dozen fans that waited more than two hours before getting the news that Shatner would be a no-show.Bikers paid $500 each to ride with Shatner some of the proceeds were donated to his two favorite charities . Ahead With Horses is a therapeutic riding organization working with severely handicapped children in the Los Angeles, Calif., area. A horseman himself, Shatner was part of the 13th annual Hollywood Charity Horse Show for Ahead With Horses and his second charity, L.A. BEST – which stands for Better Educated Students for Tomorrow – is an afternoon enrichment program for youngsters ages five through 12 in the greater Los Angeles area. The program presently serves some 12,000 children in 69 L.A.-area elementary schools.
