If you are coming from the westside of Indy take Ind 67 south to Martinsville. Turn left at the stoplight where Ind 39 goes into martinsville. Follow 39 and it will merge into Ind 37. Go thru Bloomington to Dillman rd and follow Mudpacker's instructions from there. Believe me I go from the westside to Bloomington almost every week and 67 is much faster than going 37 all the way plus it is easier to get off 465 on that exit. The bad part is that 465 is all tore up on the westside and prone to rush hour backups
