I just got back from Tempe Arizona for a business trip and what a fun town. I had no idea the dessert was so beautiful. Luckily I was in Arizona when the temp was around 50 degrees otherwize I would have probably melted. Hopefully this spring I can round up a crew and plan a camping trip to the Grand Cayon and stop in Tempe for some fun. Hope all is well. 
math paper....it's on a topic of our choice where we identify a problem and solve it. i picked the obesity epidemic in the US. not math-y....but math isn't really my forte.
