Grand County fishing

 Headed up to the mountains with Mark for a couple days of fishing.  Even though we were trying to escape the heat, it was in the high 80's even in the high country.  Day 1 we decide to fish a piece of private water we have access to.  We both start working upstream but only Mark is catching fish on his yellow pmx.  I switch to his pattern and still can't seem to get any action.  After a lot of casting I finally manage to bring in 3 fish, including a nice rainbow and a nice brown.  Mark finishes with 6 to hand and three more on and off.  Good start to the weekend!
