If you enjoy isolation, reading, (good food, at least I thought so...), a close-knit relationship with the lepalm twins, then go for it. I did a tour in '79 as a GD. Had a great time, spent off duty hours on the radio (amateur) with the Comm Rsch guys hamming it up (call sign V02HV). The work is regular, repetitious, at times a bit hairy depending on the time of year, but if you go in the summer you get to see a bit of nature (gigantic arctic hares). The experience is great, I really enjoyed it, would do it again in a heartbeat.
