I also take the bus to work on a regular basis and don't know how nobody has ever seen a woman on a bus here. The posts so far seem to be generalisations from people who do not take/want to take the bus. I personally think it's great. It takes 30 minutes from the airport to al sadd. I'm far less likely to be in an accident and do not have to waste my time sitting in traffic...I can be productive at the same time. I read, get on with some work or take my laptop with me. It's actually quite therapeutic to sit and look out the window sometimes too. I think everyone should try it at least once. I think the most annoying thing for me is when someone starts playing music or whistling along to the radio! The other thing is that I avoid taking the bus at the weekend as it's normally packed.
I'm not saying that messem should take the bus but at least be a bit more informed...look up the timetable on their website or find the nearest stop and check the times, then get on the bus and see how it works out for you. Marhaba still has the best map for the bus routes.
