D&D 30-Day Challenge: Day 29 - Most Frequently Rolled Number on a D20

I have no idea what the most frequently rolled number on a d20 actually is over my three decades of gaming - but it sure as heck isn't 20.  It feels like I could say 1 with some confidence.

My primary gaming dice are Chessex translucent red with white ink, bought to resemble my Koplow dice from 1986.  I bought four sets and keep them in a box that held Cuban cigars my friend Raul gave me on a cruise several years ago when he wanted to ditch the box and smuggle the cigars home.  I take those dice with me to my twice monthly D&D game over at Scott's place.

Damned if they don't consistently roll under 5 so much that I've taken to using my six-year-old son's dice instead.  Habitually.   Zane isn't quite old enough for full-on D&D yet, so his dice are living in my dice box lest his sister find them and lose them as she did when he had a dice bag.  So Dad kinda borrows them - and THAT d20 rolls pretty well.  All my signature red-and-white d20s?  Not so much.
