#1: Solid Ground
As in, ground that doesn’t rock beneath your feet. Sure, I got off the ship quite frequently, but it has been a full six months since I have been on land after 6:00 PM. Spending the night in a bed that doesn’t automatically rock you to sleep is a delight.
Once upon a time, during my first contract (those wild and crazy days), I had too many “cruisers” at the crew bar and ended up wasted. You think being drunk on land isn’t fun? Try it on a ship. That trick of laying on a bed with one foot on the ground to stabilize your brain doesn’t exactly work when the ground itself is also rocking. Lesson learned the hard way. I never had too much to drink again.
