Ditto on temperature control. Dosen't have to be a fridge. I have a tub that I fill half way with water, stick in the carboy or bucket, and have a aquarium temperature control set between 68F and 80F.
The original poster's beer is fine. CO2 that would still be blowing out of the dismantled airlock will stop any bugs from getting into it. Whoever said to attach a blow off tube is absolutely correct. The easiest way to do that with your set up is to stick the airlock back in and jam a piece of 1/2 inch ID (inside diameter) tube onto the middle post on the airlock (take the cover and piece that goes up and down when CO2 is venting off) off and that will give you access to the middle post. Also, there amy not be a need to run back up to your local home brew store to get the 1/2 inch ID tubeing. If you already have an siphon or autosiphon, that piece of hose is most likely 1/2 inch ID. If you don't, well then run up to the local home brew store or even home depot and get about three feet of the hose.
