Bike transport on a minivan....
My wife, two kids, and I are going to be going on a family vacation with my parents and my sister's family. We will be riding in two minivans, and I was really hoping to transport my bike with me. Is there any decent way to strap it to a roof rack safely? I understand that there are many racks, luggage things, etc, but I am not wanting to buy anything new if possible. I am not worried about security, because we aren't going terribly far, and we can just take the bike inside when we arrive.
Any suggestions? I have done some searching, but most stuff comes up with different bike racks.
Thanks
