I had fun posting hints again this year on the blog. I'm continually impressed by those of you paying attention - you got most of them. Hopefully you got confirmation of your guesses when you saw the game.
Here they are chronologically:

August 12th - Reference to Jeff Bridges and "The Big Lebowski." A central theme throughout the movie was The Dude's love of bowling. Many scenes occurred in a bowling alley.
August 15th - No clues - just a ping about the i.am.FIRST show

August 18th - More bowling clues. The photo included a bowler hat and a penguin. Penguins kinda look like bowling pins.

August 22 - There are groups of folks who re-purpose old vinyl records for a variety of things - including bowls. This upside down bowl is an oblique reference to the game name "Bowled Over." I also liked the title of the record "Learn-A-Language" - made me think about teams picking up RobotC or LabVIEW.

August 24 - The clue here was the form factor of the apples in a round basket - very similar to the starting orientation of Bowled Over's racquetballs.

August 27 - I really did take a couple days off that week and rode up the coast. The clue however is the motorcycle - it's a Victory Kingpin - another bowling reference.

August 29 - The photo of the lobsterman stacking crates is the main clue here. The post also referred to tropical storm Irene "bowling over" trees etc.

September 1 - Lighthouses are iconic as beacons. This photo shows two. The "Old and New" title refers to the fact we're re-using the beacons from last season but in a new way. Hopefully the programming skills developed in previous seasons can be built upon this year.

September 7 - Three clues were embedded in this one. Two around racquetball. I was impressed someone found the actual artwork and recognized the title "Racquetballs" of the painting. The term "hinder" was inserted because "hindering" is a category of fouls in the game of racquetball. Finally "ramping up" was in there to give a clue towards the starting locations and goals for the bowling balls.

September 9 - This Haiku was all about the points teams get for stacking the crates. On one hand it's a pretty obvious clue, on the other hand many had figured out the scoring elements but how those would be used for points based on height????
Other - I really wanted to get a photo of a boat being pushed up a ramp prior to tropical storm Irene - couldn't find one. I was also trying to get a shot of something with a Crate and Barrel store in the background. Throughout the process "Angry Birds" kept coming to mind with knocking over crates but when I tried to use shots of that they just didn't flow.
Hope you had fun looking for clues this time. Have a great season. I'll see you out there!
