So while you said Wyoming, the Yellowstone Tetons area is the only thing you specifically mentioned - is that the only area you were interested in?
What's the reason for this trip and the timing of it? As you've noted, April can be a tricky month because its still effectively winter in the mountains and most of the summer attractions are closed - although the winter ski/travel season is coming to an end. There are certainly things you can do despite the timing, but knowing your early plans will really be needed to provide any further specific ideas.
