The park was a big one here too - DD would take her bike and they would make kites to take and things. They would be gone for hours.
But DD1 liked jut being with him, regardless of what they were actually doing. So she just hung out with him for the day.

I kind of think it is important that that time they had together was not always about "going out" or "going somewhere" but it was truly just everyday things. It wasn't 'special' - it was just spending time with dad doing dad things, instead of being with me, doing mum things. ITMS.
