- It has been my experience, having done alot of fourwheeling, thus
- pulling out many stuck vehicles, that both chains and straps can be
- dangerous. The best method seems to be a strap with a length of chain
- at each end. The chain keeps the strap away from sharp edges of bumpers
- etc.which is a common reason for strap failure. Whatever your method,
- stay alert.
