Falling gas prices

It is awsome that the price of gas is this low and still falling so far. I dint think that they would drop this low this winter. It is sort of weird though. Does anyone know why they are dropping so low right now? I know that they always drop a little bit during the winter months because there is less demand but were they expected to drop this low? I haven't heard why they are dropping like this. Maybe i haven't been keeping up on my news and thats why I dont know and if so i should start watching the news. I would like to know why they are so low and if they are going to stay low. I just figured that they dropped prices so we would start using more gas again and then they would just raise the prices way up next spring and really get us. Well whatever it is i sure hope they stay low.
