Car seats...

[n86121]

Two in my wife's car.
Two in thee airplane
Two in my car.
On in my convertible.

Simple than securing and un-securing all the time.

When kids were very small one rear facing seat with wife in other rear seat.
As kids got larger, front facing seats (in rear seats).

I kept fake sheepskin seat covers - cool in summer, warm in winter,
and easy to toss/clean if the kids tossed.

Some low-cost shooting headsets, so didn'thave to worry about small children w wires, or earplugs.

Worked great
