Good write up Todd.
I feel like I'm walking in your boots, nearly identical experience, I had learnt to fly 20 years prior to building but had only accumulated 100hrs for all the usual reasons before deciding to build.
Now trying to re-engineer the cooling system at a municipal airport (not fun at all) so I can bring it home to the farm. Had 4 short flights between minor modifications where I've appreciated the multiple and long runways, but it is very easy to just leave it sitting there and do no work on it. I'm now trying to mount radiator under belly so the oil cooler can have all the cowl air. In hindsight, I should have just put it back on the trailer & towed it home.
