When you realize the only hurdles you have to get over to get your ISP operational is money.

and a 5 foot tall (about 1.5 meters) dirt plateau about half a mile away

the thing circled in red is the entire mound(it goes up 100 feet about), but in black is the ideal WISP connection route, because it is less than 2 miles away. Me and my friends are considering having 3 main hubs, each at one of our houses and maybe more at shopping centers if they want sum internet. trust me, this is going to be a shitload of work
