I snap fly fishing photos and occasionally need a person in the photo. Mainly intersted in finding someone to fish with in and arond Boulder/Lyons/Vicinity - sometimes futher. I'll cover the gas and transportation, you hook a fish and I snap a pic of it before it swims away.
A few people have been willing in the past, a few examples can be seen in the 'salt' and 'fresh' categories here: www.markpix.com
For those more accustomed to instagram than websites, @marklewisphoto will get a few examples.
