So now to answer your question, Starfish. I have done most of my test riding at Gregg's because they had the bikes I wanted to try (I had several specific models in mind) and because it's an easy neighborhood to find a reasonably clear ride route, and a hill, both of which I wanted. I did test ride at Elliott Bay but it's not a good neighborhood for an easy test ride route.
R&E let me take a bike home for several days to test ride it in various places and for a 20-30 mile ride. I really appreciated that a lot. But they don't have the variety.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
