After working around cranes most of my adult life, I feel lucky that the worst I've seen was a smashed tool shed. If you move tons at a time, foresight and planning are essential.
Hey. You. Yeah, you, anonymous person. If you logged in, you could comment, you know...
This is the first pornsite I've found in years that I'd actually advertise to swarmers. When you first load it up, it looks just like every crappy scam site out there, except that it's real. It's huge, it's updated constantly, there's no spam, no popups, and no bullshit -- and it's completely free. When you sign up through that link above and respond to the confirmation email, I make a bit of loose change.
See what other swarmers have to say about it. People love this place, so I feel fine about sending you there and am confident you will enjoy boners.
