Seth Burton was designed by Johnny Sias, but he didn't design Orange Crush. Seth Burton now has dual baskets on every hole so you can play 4 different layouts anytime there. I just played Orange Crush again last month and it's still one of the most epic courses I've played, and still crushed me physically. Navigation is pretty easy there, but a few of the long tees are easy to miss. OC doesn't get maintained like SB does unless there's a tourney near that time, but it's still playable. Beware of poison ivy on hole 17 and 18 right along the fairway. I updated my reviews a few weeks ago.
I was going to also recommend Walnut Creek, but if you are going around WV, I'd also recommend The Black Course and Timberdoodle Thicket.
Sounds like you are going to have an epic trip!
