I just thru-hiked the JMT and was disgusted in the amount of trash I was finding along side the trail. Suckers like me actually pick this trash up and carry it out. Some of the trash may be left by accident so please double check after breaks to make sure you've picked everything up. Also, please do not carve your name in the trees. Lastly, the east side of Mt. Whitney was a complete disaster (trash, poo, wag bags, etc). I know this problem is caused by day hikers and if it were up to me I would shut down this trail to day hiking!
