Biodiesel fuel!? Really?! Well, if you are careful about it, the research says it is viable, as well as street legal and federally approved. But it won’t work in gas-powered vehicles, of couse. I found a rundown on the topic from several years ago on the Car Talk web site (There’s probably better information today, but I tend to be lazy on subjects I’m not that interested in!). With the price of diesel today (and biodiesel is even more expensive!), Mark and Cherry better be pulling in big bucks to keep that station wagon running.

Meanwhile, Mark’s moment of righteous indignation and frustration gets interrupted when, for the second time, he is asked help carry the ill gorillas into the ambulance. But damn! Who knew old Happy Trail was strong enough to lift a gorilla on his own (panel 3)? I’m impressed. I’m thinking that maybe Happy Trail should not have retired.

Alas, Mark and Niecy can only watch in frustration as Gail and Guyer drive away, knowing there is no way to catch them. That reminds me:  Why would Jules Rivera apparently “forget” that she just wrote a police officer into the story a few days ago? Why isn’t he pursuing Gail and Guyer, rather than presumably still gazing at the sunset? Perhaps this is all a red herring or practical joke. After all, there is another week to go with this story, so it’s possible that the absent police officer will suddenly show up in Monday’s episode, speeding after the fleeing “wedding vehicle.”
