The San Fermin in Nueva Orleans' Running of the Bulls isn't as dangerous as Pamplona, Spain's, where daily bull runs have already begun. Bill Hillmann, the author of a guide on running with the bulls, was gored in the leg on Wednesday.

With more than 300 roller bulls in its run, the Saturday event in New Orleans promises more "gorings," but none so serious. A breakdown on the differences between the local event and the Spanish original is after the jump.
