While hiking the 175 miles into Everest base camp through the Monsoon rains, there were a couple of stretches where both sides of the trail were full of shoulder high pot plants. These were planted crops, and they looked like junk, compared to the ridiculous stuff that has evolved in Humboldt and other areas of California.
I was amused, but I wasn't interested. I had many miles to go, and I was anxious to see what I might be able to achieve once I got there.
