A very stupid, utterly insane conspiracy theory:
Al will not be touring in 2017. However, he will still be performing! He just won't be touring, which means traveling. Think about it...
Look at the equations, multiple by X, solve for Y, and carry the one...
Al will be performing all throughout 2017, but from one single location. Perhaps Al will announce at Radio City that he has signed a deal for a Vegas residency in 2017! His family could temporarily relocate there and he could see them all the time, too. Plus, we can all take trips to see him pretty much anytime of the year!
Al in Vegas, baby!

Just to be clear, the preceding was just crazy bullcrap. Al deserves some time off, and as much as we wish we could see him in 2017, I know I just want him to be happy and well-rested.

The greatest thing a human being can do is make another person happy. If I can ever help do that for you, just let me know!
