Found a stock tank I liked online.  The ones at Tractor Supply were banged up and I figured 100 gallons might be too big.  Decided on the 44 gallon.  But it arrived without a drain.  So I spent yesterday with a drill and jigsaw cutting a hole (a bit too high, but good enough). Put in a one inch drain plug I also bought online.  Then I went out to Lowe’s to get some PVC for a serious drain.  Don’t want this guy filing up with water when it rains hard.  Had to do a bit of drilling in the PVC pipe, but put some broken bricks and rock on the bottom, a layer of mesh and then three cubic feet of peat moss with a big sack of potting soil on top.  Somehow it all fit perfectly.  Going to start planting tomorrow.
