15902 Dostál           Discovered 1997 Sept 13 by L. Šarounová at Ondřejov.
Czech globetrotter Víťa Dostál (b. 1959) became a legend as the first person in his country to cycle alone 60~000 km around the world. He described the 1994-1997 adventure in Lucky Planet. A professional farmer, during 2006-2007 he made the Panamericana solo bike tour from Anchorage to Ushuaia in 223 days.
