I've done long weekends in this area a few times a year over the last 30 years. There is nothing ostentatious going on here. No charge, no gift shop no lines or crowds. It's peaceful and I always stop by and pay tribute because I walked cool in the 60's.
It just takes a few minutes to see but saying you've been there will last forever. We actually stopped off to grab a quick Geocach. I would love to meet the person who wanted to build this tribute. Stop off and say you've been.
