Spokeswoman Christy Chapman in Cleveland says the Red Cross didn't want to leave its many Amish donors out of the giveaway. The organization's Northern Ohio blood services region includes three counties with one of the nation's largest Amish populations.
The Red Cross regional operation has a board member who is Amish and who is arranging to have a buggy custom made for the contest, which wraps up Sept. 6.
Blood donors who prefer a more modern mode of transportation can win a 2010 Nissan Versa.
