The red shirts have parked outside the government house and they are talking about going to the airport just as the yellow shirt did. The blue shirts (some taxi and van drivers who want to protect their income) have camped outside the airport to stop the red shirts from coming. They off course do not want red shirts to stop the air traffic once more.
Right now nobody is sure what’s going to happen, Thaksin himself said that more news will come on Friday and he is trying to keep is big red army put. But they are most none Bangkok people and some of them do it for the money and some do not have money. The yellow shirt was much more organized and has their leader in the country; Thaksin is not here and can not support the red shirts the same way.
If they get desperate they might try to go to the airport and for sure the government won’t let them it would be catastrophe for the country now when the big holiday is coming.
