Puzzle Description:

Been away a long time. It's supposed to be a couple holding hands on the roller coaster just before they go over the top.

I posted this and now believe that it requires some guessing, but I don't know how to fix my posting. Sorry!

I think I solved the problem. Let me know. Thanks!

Extended smile logic at the very top. It looks like they are heading for some nasty green water (or that they just came out of some, depending on which way they are facing)!

Thanks for your entry! No guessing!

This got unpublished once during my first attempt (which was not solvable). This version is and is easily recognizable.

Thank you all for your comments. The green is supposed to be grass. I haven't created a puzzle in a long time and got caught up in the whole weekly challenge fever. Might have been too quick to jump back in to the deep end of the pool.

Wow, it has been a long time. Isn't it fun to be back, and to participate in the contest?

I thought this was a cute puzzle, fun to solve with the smile logic. The top was the last part to solve and that made it fun to see at the end. I hope you create some more small puzzles for us. :-)

nice image(...I could tell it was grass) :)
definitely not too quick to jump in. Take another plunge with this weeks WCP!

Found to be logically solvable by Gator.

This is a great puzzle. I really like it when people use the alternating smile logic. :)
