My budget for the bare necessities (I couldn't help it!), including food, is completely separate from my go out and have fun budget, which is why it's not included here. Might as well ask why the phone bill isn't included.
Each motorcycle ride lasts about 6 hours or so. That way I beat traffic coming and going. Same for the boat rentals. When my friend comes to town, it looks like I'll be drinking my dinner one night. These days that I go out, I take my camelpack with me, full of water, and live off that. Before I go out I eat, and after I get back eat again. I've found that I tend to eat more than I need to in the middle of being really active, and that weight carries itself in my stomach for a long time and makes whatever I'm doing a little less fun, so I usually skip eating until I'm finished.
But isn't that something to strive for? A fun and exciting time where you don't have to dip into your wallet every minute to enjoy it? I've actually found the more money I have to spend doing something (usually means touristy crap) the less I enjoy it. Theme parks, expensive restaurants, expensive vacations where you try to cram everything into a short amount of time, none of that beats seeing dolphins while kayaking in Shem Creek in Charleston, or swarms of bats coming out at dusk from a cave in New Mexico...the list goes on.
Jimmy Buffett was right. There should be a theme park where you feed mice with little Mickey Mouse hats to snakes. It'd be more satisfying than spending all day standing in line for a ride that keeps breaking down, and wouldn't cost nearly as much.
