Your other option is get yourself a regular cardboard box, split it open and lay it flat under the area where the drips are occuring...after a bit of time (determined by you), slide the carboard out and in your hands you now then have a "sample" (fresh, no less) of the fluid seeping from your ride.
If you recognize it, great. If not, take the sample to a knowledgable individual that can identify it for you.
Now, you'll be on your way to all sorts of fun and excitement.
Good luck with it!!
