Picnic Upgrade

The park provides a picnic table to each site.  Most of them are the absolute bare minimum of materials required to constitute a picnic table.
     Today I spent some time and money making the one at our site a little more human-being friendly.  The seats are now wide enough to easily accommodate the actual posterior of a normal retiree.  
     Now to figure out a way to make those seats high enough to avoid the leg cramps and chin injuries promoted by their current height.
