Timeline

I know we all say that we will go anywhere, do anything, at anytime.  But I do hope to be somewhat on a timeframe here.  See, my sister is getting married, probably June 20, '09.  As you know, you can't travel during training or the first 3 months, for a grand total of 6 months.  June is the 6th month.  So I'm really hoping I leave December or before so that I am able to travel back for her wedding!!! I hate to leave so early in volunteering, but the fact is, how can I miss my sisters wedding!? And I can't ask her to reschedule just for me. You know? I don't think it's very selfish to want this, but I hope I can relay this to the PC that I want to leave by the end of the year.  Ideally like September or October so I have at least 3-4 extra months under my belt. Of course, you can't officially pick your time, but you can preference the time frame. Anyone have any idea how likely it is I will get nominated and invited for that time frame?  Does anyone know how  filled those programs in that time are?
