Best think I can suggest on an Easter morning is:
1. Find someone who can identify for you what type of fluid this is---it's either coolant, power steering or automatic transmission.
2. If there is no such person, at least try to find someone who can check your coolant level, power steering level and transmission level for you (gas station?)
3. If the levels are OK, you can start the van up, let it warm up and see if you see anything dripping at a steady rate---if you do, I wouldn't drive the car. If you don't see any steady drips, I think you're okay for the day, presuming you've done #2 already.
