Evening trout fishing

Last Friday my wife Sue and I decided we would go fishing in the evening after work. We assembled the waders and fly rods and headed over to western Wisconsin. After a quick bite to eat we got to the river around 7:00 allowing us a couple hours of light. I had decided to go to one of my favorite spots, which must be a few other fishermen's favorite spot as there were a couple cars there when we arrived. I chose this spot since it had been a season or two since Sue last trout fished and I knew it was an easier location to fish than others. She is a novice and enjoys fly fishing, but has only cast to trout a few times so hopes were high for good conditions.
We walked down to the river and watched for a minute or two as the trout were eagerly taking flies off the surface. We decided to try a sulphur dry fly to start. I coached Sue through a few casts to warm up and refreshed her memory on reading the water. Soon enough we were each catching fish. Most fish seemed to like a nice dead drift with no drag on the surface, but there were a couple fish that seemed stimulated by a little drag.
We fished a couple pools working our way up stream slowly. The combination of low light and a strong hatch also seemed to prevent the fish from getting spooked to easily. There was many times that when casting to specific fish a different and unexpected one came up and took a fly right next to the fly line. We also didn't need to rest the pools after a hooked brown zig-zagged it way through.
The night came to an end when we could no longer see the fly to tie a new one on. This seemed like a sign to call it a night. I probably could have planned better and brought a flashlight, but I will save that fishing for some other night. We both had a lot fun and this evening got us both excited for our upcoming trip to fish for rainbows in California.
