Heh, fair enough! If you're putting in that much work you deserve the rewards. I've only got a couple gyms close by that I can take reliably, and while there's a cluster of several more in town nearby, more often than not they're all Lv9+ Mystic, and no way to I have time to take those down by myself. If I'm lucky I may happen by a few others slightly more out of the way that are often take-able (or prestige-able if they happen to be my team) but of course they require driving, and they usually still turn back over in a day or two.
