Hope everybody is alive and well after Cinco de Mayo. It has been extreamly busy and I haven't been able to put enough time into the last few posts. I am hoping that I will be able to update them all later today. Thank you for hanging in their and sharing your comments and solutions with all of the GoogleFact readers. I have a meeting again today at about 1:30 so I am hoping to be able to make a short solutions post right before I leave. I will then make every attempt to update it in detail (along with the past couple days).
Thanks again to everyone for participating, we are getting closer, there only 4 more puzzles left after today. I am going to make some comments about the final days of this challenge that I think everyone will be interested to read, so stop back by later tonight or visit again tomorrow to see how we are going to conclude these 24 days.
Post your solution to the 20th challenge in the comments below this post.
