PCT 2018 Day 5, April 27, Friday.
Start Barrel Spring Campsites, mile 101
End mile 117 tiny campsite on mountainside trail
Miles walked: 16
On the way to Warner Springs is grassland rolling like waves. 
After a ten mile walk in the cool quiet morning, the Warner Springs PCT welcome center offers hikers a chance to rest and renew. 
Run by super-nice volunteers, the center offers amenities to hikers at low cost and thoughtful economy. Home Depot buckets filled from an outdoor sink and a privacy stall built on a deck serve to make a free shower. A three bucket system is offered to hand-wash your clothes: an initial rinse bucket to reduce the dirt, a soapy bucket, and a final rinse bucket. Clotheslines are provided. You can donate your extra food and equipment to other hikers by way of hiker boxes. Snacks and supplies are sold, and rides given to the nearby post office, convenient store, and grill. Another building is dedicated as a hiker lounge, with couch, chairs, and pool table. Camping out back is free. And more services, to fifty to a hundred hikers during the season. 
And free wifi allowed me to remedy my cell phone problem. Huzzah.
After clean-up, eats, and several hours of relaxation, the trail calls. Up a mountain with more trees, until I give out and find a tiny spot, joined later by three other hikers.
Trail names to learn today: Happy, Puma, Beehive, Luco, Sharpshooter, and 2Pack.
The path goes back up a mountain on the other side of the valley, up at 3300 feet from 2200 feet, and stays up there most of the day. Cacti and yucca outnumber bushes on the south side. 
Another water cache is down a trail with shady vegetation, where many hikers hide from the heat. Finally coming down the mountain, we reach the 100 mile point. 
Nearby is a piped spring and campsites, where I get to chat with several hikers, including SmokeBreak, Julian, and a father-son team heading south because they were not able to get a permit. They tell us news of the stop ahead.
The trail will end up going over many of these peaks by end of day. The pathway uses a old roadbed for a while, level or slight grade descending, with views every step. A trail angel left oranges and grapefruit as a refreshing treat. 
I keep moving while others take a break from the sun. Water sources are becoming infrequent, so it seems better to press on and get closes to the next source. The mountains ahead suddenly look dry. 
Spoiler alert: they are.
