I'd like to ask Nancy, if there is any way of knowing why Brian came home to Florida to die. He was a Long Island bloke, his parents , also.. they were blow ins to Florida , really.. If he wanted to be helpful, he could have driven the van to Long Island, and got the Silver Service back to Miami........but he didn't. Maybe he had formed a deep attachment to Florida, then why go camping elsewhere..??
Also. .. I don't think he killed himself, I dont think anyone else killed him, I think he was just clumsy.. It's one thing to go off into the wild with other people, who tend to look after you, and open up your granola packets, but it's a whole other thing to have to chase down a frog and gig it and cook it.
I think he just didn't know where he was walking, couldn't read the terrain, didn't understand the first principles of living off grid, much less being a fugitive from justice off grid.. stepped into what looked like shallow water and down he goes. Backpack bangs him on the head. Happens a lot.
