Over the weekend, I attended the Orvis school at Dogwood Canyon Nature Park in Lampe, MO. Had a great time with only three of us in the class and a great instructor (Neal). It was hot, which made our casting instruction and fish-catching a little bit of a challenge. (Above is a pic of the first rainbow I've ever caught, and my first catch on a fly rod.) But the instruction was top-notch. I feel like I have a good base to begin my adventures in fly fishing.
I would recommend the school to everyone. Maybe not in August (it's like Vietnam down there in summer), but definitely a fun school.
