Flying

I don't mean all the crap that surrounds flying - queuing up, security, waiting, crappy food, cramped seats.

I mean the actual flying. The acceleration of takeoff, watching the ground dwindle, seeing the landscape go by, flying through and over the clouds.

For a kid raised on Apollo moon landings and science fiction, it's the closest thing to spaceflight I'll likely experience.

Not having flown for two years, the experience seems fresh again. Sadly, I still don't think our current profligate use of fossil fueled air travel is sustainable. And biofuels are unlikely to be the solution. Unless we come up with a cheap abundant source of power like fusion we may have to change our ways at some point.
