Nice, im workin on one in our 10 acre field. Make sure the logs are tight under the jumps, you don't want to be going off it and have the logs shift around! When you make jumps or even burms, pack them down real good I drive on it with an electric golf cart(batteries are freakin heavy!) or tractor with smooth tires then wait till it rains or spray it with a hose for a while, then pack it down again let it dry out completely and you have a jump/burm thats practically concrete (will hold those logs in good), it will last a long time.
