I try and have somewhere where I can land and survive when flying single engine Baby Bear, true one sometimes will be hard pressed to find such a place but I try and maximize my chances as much as possible.
For instance in the mountains if I can not fly high enough to be able to find a river valley or such to force land on I follow the VFR routes where there generally are highways or train tracks to land on.
For sure water is not a safe choice on wheels.
One will find ones self in less that desirable circumstances often enough when trying to lessen the risks without deliberately putting ones self in a high risk situation intentionally.
This is a good subject and should be carefully discussed and examined.
