Hi David,first of all,have to say what a great report,some really great photo's.
Much kudos to you and your gps unit as i don't think there would have been much people doing Ben Oss in those conditions,pretty much unnavigable using a map and compass.
Your footprints were the standard route of the day.
Anyway,until the next time,take care.(hope to see you on the 26th)
ps hope your mate's knee gets better soon
