I just saw this - so sad to hear. I only met Mike a few months ago for the first time. He saved my bacon when NRS sent me the wrong size oar, and he swapped it for the right size even though I didn't buy from him (I didn't know about him at the time).
We had quite a bit of discussion on religion, technology, etc. He was quite a character and had superb customer service.
I recommended him to all my friends, but it doesn't look like they will ever get a chance to meet him. It's too bad I didn't get a chance to meet him sooner.
