My wife tells me that all the time!
I just got my rangefinder this past weekend. I'm glad to see this post and the responses. I had no intention of trying to range an actual deer. My plan all along was to range structure and be ready when they show up. I'm terrible at judging distance.
I like Rick's post, and I hadn't considered that. Perfect situation... no wind, no obstructions and he's looking at something else... I'd take a longer shot. Maybe not 50 yards yet, but 40? Yep. The only problem I see is that if there's no obstructions, there's no cover. Getting that rangefinder out, using it, putting it down, hooking the release and getting to full draw seems like a lot of movement with nothing between the deer and me at 50 yards. I'd get busted.
