Currently, our system of informing cyclists of road closures and possible detours is through our online addenda: http://www.adventurecycling.org/routes/addenda.cfm
Also, as the fire season progresses each summer, we have a page listing road closures and detours due to fires. This year's page is here: http://www.adventurecycling.org/news/2006fireinfo.cfm
We keep this separate from the addenda because the situation changes almost daily yet only lasts a brief period in total duration.
I've posed the email idea here in the office and it's been added to a long list of things we'd like to take a look at for future improvements.
Any one else have suggestions along this line? What do you think?
