Tough question - On top of the ethics issue, rides in Colorado are running into problems with the locals due to too big of an inpact on local traffic. With the ride being "sold out", joining them as a freeloader will push them over their permit's number of riders limits. I'd have to suggest sitting this one out or riding elsewhere this weekend.
