My Trout fishing frenzy

During the last week of May, I experienced a feeding frenzy for the first time in my life. I used a fly suggested by a member and it was a Damsel Nymph. (I had never heard of this and went out an bought one immediately)
I cast this fly and within two minutes a fish had taken it, I continued to catch 4 fish in 30 minutes and had I not reached my limit that day I could have caught 4 more. It was amazing and I could feel my heart pumping and excitement building as the fish swarmed around the fly.
