HiDude is also about to hit 1,000,000 munzees so this is both a Munzee and Geocaching event

NOTES ADDED 10/20/15: There will also be an Eventzee and a geocaching event at the same time.

HiDude loves puzzles, here is one from my 5th grade science teacher:
Challenge for the kids, or the young at heart:  Bring 1,000,000 of something - and show how you know it is roughly one million of whatever you bring.

MrsHiDude's 5th grade solution to this challenge:  I typed as many semicolons as I could fit on an 8x11 sheet of paper.  then I counted them.  Then I made enough photocopies to have 1,000,000 dots.  How will you solve this challenge?  There will be a prize for the best submission.
