They've done a lot of work in and around Cameron the past 15 years actually. I remember going down there in fall of 1999 for midnight madness and the place was pretty dumpy. Construction work was going on everywhere, there was still awful carpet throughout the concourse (now it's a beautiful marbleesque? type of surface) they added exhibits, they added the new concourse on that left side that now adjoins the Duke Basketball museum they built. They added A/C, they built the Schwarz-Butters athletic center. They overhauled all the banners inside etc. Building the concourse/Museum/S-B Athletic center alone cost millions of dollars. Now they are expanding the lobby, adding an upstairs club area and increasing the number of concession stands and rest rooms. I remember going back in 2001 to partake in the Championship Homecoming (I had not seen Cameron since that fall 1999 visit) and the placed looked so much better. That new concourse area was open with rows of tables selling NC Shirts.
Cameron hasn't just been sitting collecting cobwebs, Duke has done a lot to improve it over the years. It's a great place, who wants a new arena with some Dr. Pepper or KFC or whatever logo slapped on it? Duke needs to maintain what it has and continue to improve on it.
