### Instruction:
What was the first road trip after Elson joined Indiana University?

### Input:
Elson joined the Hilltoppers staff as a defensive backs coach in 1996. He served as defensive coordinator for the 2001 and 2002 season before he was promoted to head coach. The rise to college football's highest level was difficult for the program, and Hilltoppers went 2-20 in Elson's final two seasons.

On November 9, 2009 Elson was fired by the university, finishing out the 2009 season. WKU alumnus and Stanford running backs coach Willie Taggart replaced him.

In March 2010, Indiana University head football coach Bill Lynch announced that Elson will be a defensive quality control coach. Coach Lynch noted this would mainly be an administrative role, but that he would be involved in coaching decisions. The Hoosiers made their first road trip of the year to play Elson's former team, the WKU Hilltoppers in Bowling Green, Kentucky.

Elson spent the 2011 football season as defensive coordinator for KHSAA state finalist Franklin-Simpson High School in Franklin, Kentucky.

On January 4, 2012, Elson was announced as the defensive coordinator at New Mexico State University.

On January 13, 2013, Elson was announced as the new secondary coach for the Southern Illinois University Carbondale, where he was a graduate assistant from 94 to 95. On January 20, 2016, after two years at Southern Illinois, Elson accepted the position as defensive coordinator at Western Illinois under new head coach Charlie Fisher.

### Response:
The roadtrip was to play the WKU Hilltoppers in Bowling Green, Kentucky
