This is a question that keeps popping up from time to time. Usually it's when I meet new people and tell them about the documentary. The first thing they ask is, "where will I be able to see it?"
Because of the agreement made with Loggerhead MarineLife Center, the film (in DVD format) will be sold exclusively through their gift shop at LMC's campus. That is chiefly so the film's distribution can go towards directly helping the injured/ill sea turtles at the center. 
Part of what I am doing is delivering more than 200 copies of the DVD (in cases with printed "dust jackets") to LMC. Since  am not accepting payment for the film or DVDs, they will be able to use all of the revenue for food, medical supplies and other logistical expenses related to turtle rehab.
So that's the long-winded way to answer the original question. If you wish to see Journey Home, I ask that you purchase a copy from Loggerhead MarineLife Center (please note they DO NOT have the film yet).
The other way to see the film will be to attend a screening (likely at LMC or a venue here in south Florida) or catch it at any of the film fests I will be entering it in.
But, hey, that's all still a long way off. I'm not done filming yet and post production will take a few months. I still aim to screen the film for the first time by the end of July. ...ok, that just made my heartbeat go up!

Cheers,
