1st day! We got slightly lost trying to find the way to the JMT from Red's Meadow. Only about 1/4 mile backtracking. Hike was pretty much uphill all day on sandy-like trail. Felt like we were hiking up sand dunes on a beach. We by several alpine lakes on the way. It was a tough 9.5 mile start to the trip. Got to the campsite and had to rest for about 45 minutes before I had the energy to pitch my tent. Washed out my clothes in Gladys lake. Lots of dragon flies on the lake. Mosquitoes came out in herds when the sun started setting.
