I was going to scream if the legitimate name for Alaska's high point did not register as correct. It was satisfying to type it and have it work.
The highest one I missed was Tennessee. And I still don't know it (or care much), even though I read it just 5 minutes ago!
Of the points lower than 6684, I got NH, NE, KS, MI, and FL. I know NH because it's obvious. I know NE, KS, and FL because of their comical value. The only reason I know MI is because I grew up in that state. But I never bothered to drive 800 miles round-trip to bag its high point which is 150 feet lower than where my house in NV is now, even though I'm still at a pretty low elevation out here.
That's still only 21 out of 51, though.
But maybe I deserve 21.5. I was trying to remember the name of that lump in OK, so I started typing, and the high point for KY popped up before I could finish!
