I have great memories of RFK as I'm sure many of you do, but rebuilding on that site wouldn't necessarily excite me. The land doesn't hold any special memories for me (except for a memory of playing sardine in the Metro elevator). My nostalgia is keyed to the bouncing of the bleachers, the games won, the cohesiveness and energy of the fan base, and just every stranger feeling like a member of the family.
A brand new stadium would not necessarily hold any of those. I mean there were very good reasons why the Redskins left RFK when they did. The stadium was small, it was showing its age, and lacked the amenities of modern stadiums.
So, I wouldn't be opposed to seeing a new stadium built on the bones of RFK, but I hold no illusion that stepping onto the ramparts there would transport me back to the feel of the place in the '80's. Love of a place and the culture of a place needs to be built over time.
To be honest, I have fond memories of Fed Ex Field, too, but that's because I associate it with tailgating with Huly, Pez, and the guys. I did sometimes find the sightlines tough at Fed Ex, but I never had a bad experience there. In disclosure, it may be more than five years since I last went and I rarely drink or eat concessions much inside the stadium. I do remember horrendous bathroom lines, but I figure that's the nature of the beast.
