As promised…proof that I completed the climb:
Congratulations! You earned every $.02 I paid you.

Sorry I forgot to answer earlier - I fell asleep as soon as I got home.
Yes there are floor signs on each level and there are 144 levels. About a dozen steps up (counting the landing step) each section and each landing has a sign with the floor number on it. Each landing also had 2 kid’s drawings encouraging you to “keep going!” or with pictures of animals, etc.
It goes by faster than you’d think. I still can’t believe I didn’t rest at all - just kept on truckin’ up each floor. My legs actually felt better when I was walking up the steps than when I was walking along the flat landing. They’re pretty sore right now though, delayed reaction LOL.
Thank you!!! 
Beat it! Awesome! Did you know you were close to breaking 25 as you neared the top?
Did you have to elbow a lot of slowpokes out of your way?
I remember that feeling.
Climb…climb…climb…climb…THUDTHUDTHUDTHUDTHUD…climb…climb…climb…climb
Did you get the jimmy legs at the top, where your leg muscles still want you to keep climbing?
I had no idea of the time, just that I was doing pretty good. 
Nope, the slower people stayed to the right and the faster people to the left. Actually I met some random girl walking to the tower and we hung out all morning - she was right behind me then passed me at floor 99 and was about a minute ahead of me at the top.
No “jimmy legs” - but I do know that feeling after a run - I think I was just relieved to get it done!
Do the stairs turn left or right; were you passing on the inside or outside?
& congrats!
They turn left as they spiral up and people generally stayed to the right and passed on the inside, but it didn’t really matter. They let just a handful of people go at a time so the stairs don’t get congested.
…and thank you!
