For the young dads reading this, pay attention!
When my daughter was 4 and my son 2, we took them to Anza Borrego desert for the first time. I pulled the little camping trailer I have listed in the classifieds behind Ruftoys.
While my wife held down camp with our son, I took my daughter out for a slow-speed cruise across the desert with her sitting on my lap. She helped hold the steering wheel
I casually reached over and tipped the rear view mirror until I could see her face. Then I just as casually let go of the steering wheel, watched and waited. When she realized that SHE was driving the cruiser, her eyes got as big as saucers! An absolutely priceless moment every dad should have.
