Any favorites?

I am big into field collecting, mostly in a way that includes me finding, capturing then releasing shortly after. I have had many fun adventures, times where I could hardly keep my heart behind my chest. I remember this one time I was out fishing and came across a garter snake that measured almost 5ft! This garter was huge, I couldn't believe it. I went through thorn bushes and a nasty marsh to capture this guy. To this day I regret not taking any pictures. There are many other times that were close, like the first time I HAD to capture a timber rattler, but that story is for next time. Anybody out there have any good collecting stories, or where you just came across something? Whats your favorite you've collected so far? I have too many to count!
