Hi David!!
I also like the mountain, I live relatively close to the Pyrenees.This weekend I was for bujaruelo, the tones of autumn begin to be intuited a bit
I carry insulin bomb and one day reading the recommendations of the Pump Lei that was not recommended for altitudes above 2000 or 2500 (I did not turn) a little worried, because the previous week I had uploaded a 3000 and in winter it had been in winterThe Alps and the apartment had it at 2100 meters.I called Roche and they didn't know howHe said the same was for the batteries, that he has to take two games of batteries for the machine).Do you know anything about this topic?
