What happened at Site B?

So we all know about the huge fall out from the first Jurassic Park on the first island, dinosaurs broke out and it was abandoned.  But what was the case on Site B.  For all intents and purposes that seem to be running just fine we never heard of any accidents, but in the 2nd it is completely abandoned and there are no bodies to be had.  That might be a good idea for a 4th movie.  Show what happened at Site B and why it was abandoned by all the scientists.  Unless Hammond decided to just pull the plug on everything after the first one.   

Why does he pull the plug so easily?  He made dinosaurs, one hiccup, and he quits, how did he become a billionaire.  He is even still defending it to Malcolm in that bunker talking about Pirates of the Carribean, but then 20 minutes after that, lets forget about everything on the park.  Something doesn't sit right.  I guess he has that part where he wants to go back when they are taking off in the helicopter, but that's it?  Just send a team in take down the T-Rex, forget about the raptors, or genetically engineer them to be smaller, just make brontosaurus and shit.  It could at least be a decent vacation resort.  I'd probably go there even if there weren't dinosaurs, he had a pretty good setup and good locales.  You have a secluded island go with it.  Turn it into the America's version of Bali. 

How many people died that we know of, maybe 5 (worker in the beginning, Nedry-deserved it, Muldoon, Gennaro, Samuel L)?  How many people died building the Panama Canal?  Great Wall?  So basically these people will have died for nothing by just abandoning the park.  Run the park, get revenue, give a portion to those families, and you could build great charitable organizations through the revenue of it.  "Nature is too awesome to control"  they are just dinosaurs, animals, just need to have fail safes so someone from a single computer can't turn off the power to everything.

 The raptors were a huge fucking mistake.  The worked well and looked sweet for a movie, but for a theme park maybe not.  They are not as mad as the Xenomorphs, but looking how they go in the movie (except the 3rd), they are closest thing on earth.  Plus they just put them in that pen, how are people going to see them and interact with them.  

Or why not forget about the dinosaurs just turn it into a genetic research facility, develop cures, stem cells, engineer organs.  You have millions of dollars worth of equipment.  Put the Lysine contingent into effect, keep around some dino embryos just in case, and start on a new project.  What a quitter.
