I'm one of those A/R kind of guys that likes to analyze everything. After each of my road trips, I tend to look back to see what worked and what didn't. I always tend to over-analyze past trips in my mind to see what we liked and what what we would want to do differently (if we go back). This last trip we did a lot and I am not sure I would change much. I did not make it up the Space Needle, but in hindsight, that was not a big deal (sure, paying $25-30 to ride to the top of the needle to see a panoramic view of the Seattle area is nice, but we saw lots of great views from our vantage point). I would have liked to take a day to go to Mount Rainier and hike some of the local trails. I made it a point to sample some of the local flavor (i.e. breweries) and we were going to try for a winery or two, but just ran out of time.
Got to spend a lot of time with junior and even got to see my brother & wife, so I would call the trip a success.
