The gentleman that got killed worked for Bell. This from Velonews.

I read somewhere that crud in/on the roadway (gravel, mostly) contributed to this accident. Having ridden in the same area where this group was riding, I can vouch for the scariness of the road conditions. Hopefully the sweepers will come through before cycling season goes full-on (and hopefully we're out of the time period where the road crews need to put sand/gravel on the roads). Very sad!
