Jeff,

I hope you are aware that the RAGBRAI route changes every year.  And that is
not just adjustments to the route but rather completely different routes
each year.  While routes may repeat after a few years, if you did the
RAGBRAI route every year you would eventually show a large fraction of the
east/west roads in Iowa as being bicycle routes, or at least RAGBRAI.

I know that in the past there has been some interest in RAGBRAI among
OpenStreetMappers (if you're not familiar with RAGBRAI it's best described
as a week-long moving party where to have to ride your bicycle from party
location to party location).  The detailed route was announced last week, so
I thought that it would be interesting to study the route in more detail by
building up a route relation in OSM:

http://www.openstreetmap.org/browse/relation/2821829

On one day there's an optional route (called the Century Loop or the Karras
Loop) that brings the day's ride to 100 miles if you take it instead of the
normal route:

http://www.openstreetmap.org/browse/relation/2821877

The route between towns is pretty well fixed, but the route through larger
towns might be adjusted later.

I'm hoping that I can attract some armchair mappers to help fix up the TIGER
deserts that the route goes through.  Bing has pretty good aerial coverage
of the entire route so it should be fairly easy to align the streets and
clean up any obvious errors.  I'll be doing what I can between now and the
end of July, but there's a lot of work to be done.

Also, what's the best way to share this with non-OSM people?  The route is
starting to be rendered on OpenCycleMap, except that it doesn't show up at
the scale I would need to show the whole route (and might get confused with
other routes in the region).  The following URL doesn't work for me for some
reason:

http://www.openstreetmap.org/?relation=2821829

I tried both Firefox and Chrome and the map area just stays blank...
