Since most people are guessing, and a few have their strategy, I thought I would share mine. 
 
Originally, I was going to collect everyone's guesses and make mine on the last day based off of averages, gaps, etc. So far, I have 730 guesses in about 18hrs, and no desire to keep collecting data. For fun, I thought I would share what I have seen so far. This is all at the time of my post. 
 
The guesses range from 6.3lbs to 4,271lbs. (I converted all kg guesses to lbs)
the average is 101.8lbs
The most common guess is surprisingly 13.5lbs (5 people)
50% of guesses are under 56lbs
 
Now, my guesses. 
1. 101.9lbs (someone guessed 101.8)
2. 215lbs 
3. 81.7lbs
 
Thanks for the contest and the opportunity. It will be fun to watch. 
Best of luck everyone.
