We will meet at the trailhead for Little Si at 8:30 am.  If anyone needs to carpool we can meet at 8:00 at the Tibbett's Park & Ride across from the Issaquah Transit Center.  We will want to be geared up and ready to go at 8:30 or shortly thereafter at the trailhead.

PLEASE NOTE that to do this trip you will have wanted to do at least 4 other trips of a 2,500 ft. gain and 5 to 6 miles at a moderate pace with the Mountaineers.  We will have breaks as needed for clothing adjustments and hydration or snacks on the way up.  We will have time for lunch at the top and right now the weather is looking clear for Saturday.  You will want to be sure you are dressed in layers as we are now in to our winter weather.  Please bring your Ten Essentials and wear over the ankle hiking boots (no tennis shoes or trail runners).
