He also said they only do vertical systems now, mostly because they work with a drilling company that's just as cheap as doing horizontal and there's less mess...

That's good info to know.

I have plenty of land to dig horizontal, but am mostly leaning toward vertical bores because of the flexibility it leaves me. The south half of my land is a motocross track that I ride in the winter. If I dig in a bunch of horizontal pipes, I'm stuck with the lay of the land for fear of damaging the loops with a dozer. I like to change up the track layout every couple of years, and I would hate to stress out over the pipes. The bore holes can be placed fairly close to the building too.
