MBWorld.org Forums - power stearing fluid

Yesterday pulling out of my parking spot at work something busted with my power stearing fluid. In a matter of seconds it was all gone. I would have less than a mile to the dealership which i would rather smash all my fingers than to take it there, or a few miles to the only other place i know that fixes these cars and has had my/my familys cars for a while. For the last few times i have had it in there i havent been pleased and i think he is to busy for his size anyway. Plus he isnt answering his phone right at this moment anyway. What i want to know is how far can i take this w/o burning something up, or should i just have it towed to where ever it goes?
