While there were no large sticks to brace the door with, there were several large rocks that could be rolled in front of it.[/i] With a DC 15 strength check, that is.
I uberized my Str remember? ^_^
Even with 5 Str damage, I have a push/drag limit of 2,300 pounds. wiki.answers says landscaping rock is 1.4~1.7 tons per cubic foot. if each rock is less than 1x3x5 in size (ie almost big enough to cover the entire door), I could push it over under carry limits just fine.
The real problem is being disabled through, so moving the rocks would probably kill me.
