Any one in Baltimore Area running WVO?

If there is anyone in the area running Waste Vegetable oil I would really like to meet you and check out your vehicle especially if you converted it yourself either way I really want to see this up close and personal. I am also intersted in the filtering/ processin setups that one might have at home. I am very intersted in this but I am a little skeptical as to how feasible this really will be for someone like myself who lives in the city. And by the way to run Waste Vegetable Oil in a Jetta TDI do you need to and chemicalls and a bunch of other stuff I really don't know how to do?
