I just got my track dozed out on my Property. I have some really thick woods that weren’t being used so I decided to have a bulldozer come in and doze me in one. I still have allot of work to do on it. I figure I will rent a skid steer and build corners and jumps. This is right after he left with the dozer of three laps around it. Anyone else have one they built? Give some tips on the easiest, cheapest and best way to finish out one?
Then again not sure how big/many jumps you're wanting. You're also going to want to put a layer of hard pack (think clay mixture) on the face of the jumps unless you want to be refacing them all the time. Another thing to remember if you go big is since the trees are so close you might want to trim some branches, if there's a chance you might hit them. 

You are probably on a few hours from where it is if you are up in N. Indiana. My place is in Battletown KY. Once I get it done, might be next summer as money and time permits you can come down and ride it.
If I remember right he got the dirt for all the jumps from his irrigation pond. 
you must be way up there. No problem here, it is all country, make a weekend party. barn fires, beer and bikes
Maybe stop in next year after Loretta's, practically go right past your house on the way. (I65)
