I got my Toyota Camry Hybrid stuck in a grassy/muddy area on a Saturday mid December. With the rain and fog, the tow service was unable to get my car out, fearing that they would also get stuck. After the rain stopped on Sunday, I waited three days for the muddy 80% grassy 20% to dry out. When I arrived on Thursday, the ground had not dried up completely, so it was still soft in some places, but not muddy. The depth of the front tires sunken into the mud was around 3-4". In order for this to work, I had to dig out the mud, front and back of the tires on all four. It wasn't magic, remember the tires are sunken in front and rear and the car is already low and very little ground clearance, so there was some digging with my hands and shoveling necessary to maneuver the Recovery Boards underneath along my front wheel drive tires. Note that since my car had some sort of traction slippage control built into it, it was a disadvantage hate to say when I tried and wanted the tires to accelerate. So with the mud and slight slippage, i got almost no power to the wheels, arghhh! After several maneuvers of the Recovery Boards and not giving up, wheww! The final position was getting the tires onto the boards, closer to one end of the boards. That way, I had some room to roll and accelerate the opposite direction, (which was reverse for my case), which got me out of hell, haha. Without these Recovery Boards I wouldn't have gotten out. Also, a big thanks to my friend who was there to observe, analyze and give me key suggestions what to do and not. We did it! Thank you
