suggestions for keeping the driveway clean since my 240 leaks..!?

[wilburtual]

my landlord just told me in a very FIRM way that they didnt appreciate my ol 240 dripping on their brand new driveway/parking lot.. which i then said (in my head) arent parking lots for cars to park? but anyways...
while im tracking down my leaks (i think a little fuel, a little oil) im wondering if anyone has suggestions on what to lay down on the driveway to catch the drips? its only a few drips everynight, but over time its created a pretty stain collection of drips...
im not sure exactly where the drips are coming from, and some kinda seem to be random (prob getting on things while driving and then dripping when i stop) so it might need to be a larger surface area than just a small drip pan, since it seems to drip in a different place sometimes... i was thinking maybe cardboard or an old carpet, but that would get nasty in the rain ...
