I brew in march (second time coming up) and drink it at Oktoberfest. I kept it keged 1/2 pressure off gas in my lagering fridge, as long as you got something else going it's easy to just leave it alone and forget about it. Well worth the work if you have the facilitys.
But, I will say mabey concider doing a shorter lager first, either a Vienna or a Marzen to drink right after a regular lagering phase. Make sure you got good product coming out before you dedicate half a year to waiting for it. My second brew ever was a Lager. Realy great beers to make.
