Normally the words "double-cross" would evoke a sense of betrayal, something you would not go in search of. This time around, no worries, it is all good! Seeking to "double-cross" has been a well thought out, carefully considered, plan to attack!
Well, it can be all good as long as you are prepared! I added a BlackDiamond Cosmo to my collection of required gear. It is my, just in case, safety insurance. The plan is to keep it tucked away but when the itinerary calls for a 15km "double-cross" on Saturday who knows what artillery might be needed!
