The biggest biker party around starts today.

All around Southeastern Wisconsin, more than 100,000 riders and Harley-Davidson enthusiasts get to enjoy dozens of official events, and lots of other tie-in activities, connected to the Harley-Davidson 105th Anniversary Celebration.

Many of those riders are converging today from all over North America as they arrive on official Harley-Davidson "Ride Home" journeys, from New Jersey to San Diego to as far away as Mexico City.

And they'll enjoy the best entertainment this side of...dare I say it in case Harley fans from the 100th celebration choose to regurgitate...Elton John:

Bruce Springsteen and the E Street Band, the Foo Fighters, ZZ Top, Kid Rock, Foghat, Joan Jett and the Blackhearts, Amanda Overmeyer (of American Idol fame) and - cue the cowbell - Blue Oyster Cult.

They're performing at everything from the "Roadhouse at the Lakefront" to street parties to the Summerfest grounds to Wednesday's opening party at the Harley-Davidson World Headquarters on Juneau Avenue.

Plus, there's the awesome sight - and sound - of thousands upon thousands of Harley riders going right down Wisconsin Avenue on Saturday morning.

Get your earplugs if you need, Milwaukee, but enjoy the party!
