The easiest way to get there from anywhere North is to drive to Indianapolis, take the 465 to the bottom of the loop and exit on 37 South. This goes right past Bloomington. Get off on College Avenue (the first Bloomington exit) and you'll be on on the ascii map.
Coming from the East or West (assuming you are South of Indianapolis), 46 will bring you into town. From the East, take 46(3rd St) until Jordan Ave. Then go north on until 7th St. From the West, stay on 46. It will eventually become 17th st. Then follow the map.
