Willis Tower

The Willis Tower in Chicago (formerly the Sears Tower) is a 110 story skyscraper. When it was completed in 1973, it was the tallest building in the world. I love the observation deck - walking out in the plexiglass cube and looking straight down... and the people who literally crawl out to the edge of the glass, peek down, and then scurry backwards.

I would definitely be one of those people who don't want to walk out on the Plexiglas, , that is if I dared to climb to the top in the first place!!
Thankfully B and R were braver than me and found their way up the tower.

Fun relaxing logic level with your usual nice touch in the design...Thanks for sharing @D.S.Masters
Btw,lately you are very productive ... and I like that ... keep it up

Very enjoyable puzzle.

Not bad..

@delator77 Yeah, I had just posted "Rube 2" when the idea for "Rube 3" hit me, and yesterday afternoon inspiration struck in the form of the R moves and the steps on the central section. (shrug)

@meko I'm not good at difficult levels... and heck, I do this for fun.
