Ruffed grouse and woodcock go together like peanut butter and jelly. But add a third species to the bag like sharp tailed grouse or spruce grouse and now that walk just got really interesting.
In recent memory I have had two walks stand out. One in the Dakotas with pheasants, a hun and a sharpie. The other in Minnesota with a sharpie, a ruff, and a snipe.
I have had many times where I have encountered the third species but for whatever the reason (mostly my poor shooting) did not get the third species.
I love the single walk hunts. I'll walk extra miles where I feel it's less likely to get a last bird just to avoid wasting any daylight driving to another area. Probably my biggest regret was a walk in Idaho with a chukar and three huns and flushing a ruffed grouse from a stream bottom while I was aging bear poop. There have been many days in the inter-mountain west that I could have added a valley quail to chukar and huns and thought I'd wait till it just happened. Well, it hasn't. I'll have to clean up some of those episodes of poor judgement before I can't make the walks anymore.
