de_airstrip is a weird map, dull sort of, its really uneven for the terrorists because they are forced to go to ONE bombsite all the time because the other bombsite is the ct spawn, not next to it. It's the ct spawn.
One bombsite in de_dust is the CT spawn. Btw, I'm dl'ing steam right now.
Like 80% of de maps have one of the sites in the ct base..
