I find some with metal detector. if I'm in grass and have an idea what area they dug into i walk around barefoot and can usually find them. this has helped in an area where there was metal pieces scattered from construction or litter making the detection hard to do
I used CH1 on Colorado hunt this year. at first was scepticl6if they had enough support. after 11 days hiking in them have to say I was impressed with comfort and how they held up.
