I'd say Martock is more likely the weekend of the 17th. They will not have enough coverage/depth by the end of this weekend to Open well. It won't be like the years with joey where a 2/3 covered trail was considered open.
the word from the snowmaking crew is that the hill is "striving" to open this weekend, and i was at hill lastnight, and i saw thow muc hthey had made and i think it is possible to open, as long as this warmer weather doesnt do to much damage
