Ok this is a bitter one… I know one very arrogant engineer that thinks that this hill is real… Well it is not! It’s actually free as I found out for motorcycles! Why do you ask… Well it doesn’t work quite right for motorcycles… The simple fact is that the white post which you may not be able to see is actually about 10 feet higher in elevation than the beginning! So, when you head to the “bottom” your not actually at the bottom… There are two hills, a valley if you will… In fact today was quite rainy and well wouldn’t you believe it… the rain flowed both ways… There is a valley… The reason why cars work better is because they carry more momentum, and make it up the second hill… My meager 1000 lbs. didn’t quite make it up the second hill, hence why it is free for motorcyclist… Sorry to burst your bubble, and yea you don’t believe in ferry tails… ha ha… I think you do…
