Runway 20 in use?

[cka411]

I've noticed over the past few days that runway 20 has been used and 25L hasn't. Is there any reason for this? All I can come up with is weather conditions. I've noticed again and again, planes flying right over my house, they normally do, but this time from the north east. The United flight has been flying over every day around 1230 as planned, nice to see I can say! Does any one know how long they will do this?

I am probably going to go spotting Friday, if they are using 20 still, will my small 6.1 times zoom is the hill next to to 25L a good spot or in the woods next to the 2 a better spot for such small zoom?

Probably the 20-t/o have to do with the works at RWY25R-07L. Normally it'll take till 22 August 2004. Some more info available:
