I'd like to run a prize based promotion in the USA -- and looking for suggestions on legal constraints, responsibilities, and documentation required to execute one.
Yes, I know there are lots of rules, and they vary based on where the person enters the promotion, and if selected, where they receive the prize -- BUT someone's got to have some experience and/or suggestions to get me rolling in the right direction.

I don't have any experience about the US view, but you might take a look at the rules for things like raffles to see if that helps.
As you say, it varies from state-to-state. That first link has a list for most states, though. For example, Connecticut's link takes you here.
