Is it really almost over?!

I can't believe that there are only four episodes of Battlestar Gallactica remaining! It seems odd that the series is really coming to a close, considering (a) the strength of this final season and (b) how much remains to be resolved. How can the show really fit everything into four remaining episodes? Regardless, I've enjoyed the ride, and, while it's never good to see a beloved show ride off into the sunset, I hope it walks away with its head held high.
