RE: Romper Room Ride Earlville Ia.
I haven't been on it myself, but a guy I work with has done it the last couple of years. It runs about 230 miles. There are usually bands in every town, troughs full of beer(not sure if free), and food. Police and state troopers have intersections blocked off so you don't stop at any stop signs or lights. Last year there were around 600 bikes. This year they are expecting around 800 if the weather cooperates.
A lot of people spend the night around Earlville or Dyersville at the end because it's a pretty long day.
Maybe contact the Tri State Raceway and see if they have more info
