Here is mine for starters...
Let me first say, this is the first time my wagon has been stuck, I've always been the rig of choice for recovery of all manner of other stuck rigs.
While trail riding in northern MN last weekend I managed to do this to my rig while crossing a old beaver dam...

The thing really dug it self in... I was in 4 low but not locked front or rear when I went in... once in I locked front and rear and just dug it in deeper.
Let me layout the recovery tries and there results...
#1 30 ft strap connected to a Grand Cherokee, full launch with 10 ft of slack... didn't even shake the wagon.
It did manage to move all his camping gear from the rear storage area to the front seat however!
#2 Dig, Dig, Dig, air down tires from 45 psi to 25 psi, single line the winch (12,000 lbs)...
closest tree over 200 ft away, so we tied the winch to a Toyota Tacoma with front and rear receivers then tied together 2 tow straps and finally a 6" pine.
Winch pulled to a stall, only after pulling the Toyota back 3 ft and starting to tip the pine tree over!
The wagon never moved. damn it really is stuck!
#3 Dig, Dig, Dig some more, double line the winch (24,000 lbs)
Tie the winch to a mid 70's Range Rover, then tied it to the Toyota, then tied it to two new pine trees.
The winch didn't stall, preceeded to pull both the Rover and the Toyota and tip both trees ALL AT ONCE!
Starting to worry...
#4 Tie on to the rear, after more digging.
Used a 30 ft strap with 10ft of slack connected to a huge model 110 Range Rover (think suburban size Rover)
We managed to pull the Wagon back 4 ft... yes! we are at least free!
#5 Filled the ruts with logs and sticks, dug out more slope, connected the Range rover and Toyota with 30 ft straps each to the front of the Wagon.
We had 10ft of slack in each of the 2 tow straps... worked the timing so the Toyota took off, then the Rover, and I nailed the gas on the Wagon as the whole thing got tight.
Wham-O, the Wagon leaps out of the hole! Free at last, free at last!
Total time = 2 hours
Total man power = 8 guys
Total vehical count used = 3
Cost = 2 cases of beer that night at camp!!
Priceless time had by all...
OK, guys top that....
