It's been a while since i read that and I forgot, they don't always own the property they dig on... a lot of the time they are contracted by other peopel who stumbled upon dinosaur bones on theor property and so they go to those places too. where they find one, they often find more.
A comment on their registration page (you can join them if you'd like) says this: Too many bones found and we need your help to get them out So come join us !!!
