If I’m not getting any otherwise, the Holodeck = sex time. Assuming I am getting laid, then I’d do a variety of things in the holodeck. Play LB for the Saints. Pitch or play 3B for the Braves. Pin Ric Flair for the NWA title. Box a few rounds with Tyson. Fly dogfight missions in every fighter aircraft ever made. Drive an Indy Car race. Or a NASCAR one. Play tennis against McEnroe at Wimbledon. Ride next to Rooster Cogburn, and face Ned Pepper’s gang with him. Lead Pickett’s Charge. Ride with Mosby. Raise the flag on Iwo Jima. Storm the beaches at Normandy. Defend the Alamo. Ride with or as Josey Wales. Etc. Basically, it would be a Virtual Valhalla.
This could be exceptional. I’ve had an ongoing thought about riding a mountain bike on the moon. Or other low-gravity place. In a vacuum.
My guess is you could go really, really fast. The holodeck fixes the otherwise insurmountable problem that I would kill myself in the first 20 minutes by biffing a jump and tearing a hole in my pressure suit. I have no ability whatsoever to land a big jump, and the exhilaration of easily flying the bike would be very difficult to resist.
BTW, I have only recently experienced being able to make my bike tilt forward in the air to get the front (steerable) wheel in contact with the dirt first. It was on a tiny jump, and is undoubtedly a basic move, but it makes me feel all studly whenever I think about it.
They’d had to pry the holdeck from my cold, dead hands.
Even discounting all sex-realted stuff, D&D, sports, rac cars, playing in a rock band, flying, you name it.
I live long enough to realize it and shout Valhalla, I am coming. I hope.
Otherwise, I’d assume everybody would have to line up while they shoot my corpse out one of the torpedo tubes, and maybe play Free Bird for me. Or if there wasn’t much of a corpse left, just recycle my atoms into the system. So there might be a little piece of Oak in every future holodeck program.
Hiking with great vistas and no mosquitoes. Sandy beaches and tide pools. Touring historical gardens. Maybe with a tour guide or other cadets, maybe not.
D&D for me big battle, beautiful vistas, beautiful women that start out half naked and end up completely naked. Occasionally I’d do some 21st century stuff but only for the big explosions.
