[IKE]

I instpected (and was LRI) a lot of events this year. I only saw a few failures of the plywood itself. 2 due to wrong material (0.5" plywood and regular pine board). I did not see the 3/4" plywood failure, but I did see the bent frame behind it. They had bent their frame utilizes a couple pieces of 1/8" think angled.
Most typically, I saw failed mounts, or failed joints due to poorly fabricated items.

With a note on "flip-flop" bumpers. I saw some beautifully constructed flip flop bumpers. They were wonderful to look at and use. I saw many poorly constructed flip-flop bumpers. Typical issue:
1. Not full coverage, IE ends still show significant amount of other color.
2. Flip flop so easy, the robot changes colors mid match!
3. Sagging flaps. When the flaps are down, they frequently have pieces that are clearly below the bumper zone. Refs ask me, and I explain it was in the zone during inspection, refs are clearly agitated, and I have to work with a team to make it better.

FYI: As an LRI or Head Ref: having a saggy bumper non-compliance at an event is a lot like hiking with a peddle in your boot. You don't notice it, and it will bother you at the least convienient times. Until you completely take care of it, it is a nuisance that will show up several times throughout your adventure...
