Completed Marsimek La on the second attempt day before yesterday. My plan is complete. Will do it again in a more leisurely timeframe in the summer. Some notable points:
1) Zma gave out just after the ITBP checkpost near M-La. Ditched the bike in the snow and hiked up to the top.
2) Everything covered by snow. No boards visible as everything was under 4 ft of snow, so i have taken a GPS reading to make sure i actually did reach M-La
3) Roads till Pagal Nalla are in fantastic condition.
4) Cellphone connectivity (Airtel) available even in M-La, and K-Top! Got quite a buzz calling hisunil and gsferrari from M-La top
Will share more when I am back in Bangalore.
