I went for Peterson vs Khan, and it was almost sold out, so little chance. Khan has a huge following in and around DC, I was very surprised. I wouldn't know what to expect from this event. I would think it is pretty hard, if anything like Khans fight.
edit: we had the cheapest seats, but could see fine. Relatively small venue.
Peterson Vs. Khan was at the DC Convention Center I believe. I've been to the armory to see Hopkins V Shumenov. The armory is a smaller venue and the cheap seats are not bad at all. When I went there wasn't too many open spaces lower than myself to move into to answer NAC's previous question
Just rewatched this card. The other times I watched, I missed that Vargas was trained by Dewey Cooper, of k-1/kick boxing fame. Pretty cool
