Centerboard stuck in trailer

All set for a beautiful day to sail my DS II when I got a bad case of the stupids. First, I went out with the bilge plug in my pocket. Does anybody know how much water the DS II will hold? I'm guessing a hundred gallons easy!!!! It drained for at least 20 minutes. Really impressed my wife with that one!
Later in the day, I decided to give it another try. I remembered the bilge plug but, for some reason the CB dropped as I was launching and is now firmly wedged between the axle and cross member of my trailer. Anybody have any ideas about how to get it loose other than getting a crane and lifting her straight up? I tried to float it and pull it forward but it didn't work. All this on what was probably the last decent sailing day of the season.
