You can catch up each day by reading The Green Monkeys here. I've started doing the dailies again, not that I have the time, but I've so many requests from friends and fans who read it weekly in Dan's Paper that I had to start it up again.
You can also find a kindle book of their adventures at Amazon that looks great on an ipad. Full color from about two years of the weekly comic are available. Let me know how you like the daily. Okay, back to work.
