I don't see much information anywhere about people arranging carpools. I'm aware of this site https://g.clouthub.com/group/patriot-caravans-for-45but are there any others?

Me and a friend are looking into flying into Philadelphia because the flights there were around half the cost of flying directly to DC, but if we were to fly there, we would be reliant upon a local that's already driving there to pick us up. Could somebody point me in the best direction to inquire about such a thing?

I'm not a wealthy person, and I don't want to freeload and inconvenience other people, but I just can't afford a 500$ plane ticket + hotel and food and transportation, etc. I'd much rather go with somebody who's going there for the day, I can throw them some gas money, and we can maximize turnout. I'd appreciate any help or advice in this area! I'm sure there are some patriots out there willing to help!
