As of Aug 2, 2013, I find conflicting info on how to track the 10/15/25 mi rides.
I suspect the 50 mi tracking is also not alligned between the two documents.
The text on the wiki web page tracks rides as 7.a.2 & 7.b.3http://meritbadge.org/wiki/index.php/Cycling
It describes road biking and mountian biking options.
It claims to be created from the official source, Boy Scout Requirements, 2012 Edition (BSA Supply No. 34765)
It points to the workbook .pdf :
The workbook .pdf tracks only road bike rides as #8http://meritbadge.org/wiki/images/b/bf/Cycling.pdf
and does not mention a mountian biking option.
It says the .pdf was upaged in May 2013.
Can someone clarrify so I can put the correct requirement # on the blue cards?
