Before I went to bed, I had to flip through channels one more time. While I was watching ABC 13-KTRK's coverage, the reporter was talking to a refugee and during that conversation, a producer or other reporter broke in, audio only and said that the buses that were there were being allowed in.
I wish I could post more but I wanted to post this as fast as possible.
Update [2005-9-2 1:36:18 by kineticdissent]: They also showed footage of inside the Astrodome. The ENTIRE floor is covered. (if you've ever been there you know how massive the floor is) They are saying they will accept these buses tonight and that the main problem they had earlier (and the reason they tried to stop accepting buses) was because they are low on volunteers.
here's some Houston media sites.
