I would imagine it's like climbing Everest, and having to walk past the remains of other climbers who didn't make it. I'm not very religious, but I did say a silent prayer for the people who died in the wreck... What I find interesting is that "time-proximity" affects how much we might feel about being in or around such a wreck or site. I've been on WWII wrecks where people died, but never felt the same level of "weird" as on the Salem Express. Like finding the skeletons of some ancient people - the excitement of discovery probably outweighs the feeling that you're desecrating a grave (Richard III comes to mind for you guys in the UK).
When I go, you guys feel free to strap me to the mast of some sunken ship with my full scuba outfit on for future generations to gawk at... Just make sure I'm wearing a rEvo or a Meg... :devilban:
