I'd say all three units have quite a bit of pressure but Ironton maybe the least, those hills shouldn't bother you considering where you are coming from, I live near the Ironton unit, make sure you travel up state route 93 and get a bite to eat at one of the several places in oak hill. If you need sporting goods you can get anything you need at Lakeview Grocery and Sporting Goods which is right outside oak hill on StateRoute279 beside Jackson lake, there's a campground at Jackson lake also, check out the oak hill area chamber of commerce's Facebook page for more information, we have our visitors guide and business directory posted on there. If you have any questions on the oak hill area message the Facebook page and I'll try to answer them. I'm the president of the chamber. Good luck and enjoy the area.
