I will post all the details soon (a journal full of writings to transcribe - and reduce!) but just to say that Aconcagua was a wonderful adventure. I didn't make it to the summit unfortunately... 20,000ft was my limit... got pretty sick for 2 days but recovered to enjoy the last few days hiking out. Back here in Mendoza since Monday night and flying home today. Not looking forward to the Mpls weather after basking in warm sunshine almost every day of the trip - we really got lucky with the weather even on the higher parts of the mountain.
