First - the caveat: the schedule below will not be final until submitted to,
and approved by, Randonneurs USA. But - here's the current proposal for the Desert River Regions rides out of the Tri-Cities:
200km - Mar 5
300km - April 2
400km - May 21
600km - June 11
We plan to use close to the same routes as previous for the 200, 300 and 400. The 600 will be a 'bow tie' centered somewhere here out east (Richland, or Prosser, or Walla Walla, or Hermiston, or...).
