Bike rack front vs rear

I put a hitch on the front of my truck and a 3 bike carrier. There are no issues. I can see just fine and the headlights shine through the spokes at night. Mine was a bolt on, no drilling required. Pretty sure it is a Curt. The only down side is that when there are no bikes on it, I cannot see the bike rack, so I added a driveway marker (orange and white stick from Lowe's) to the the front so I remember it is there since the rack sticks out about a foot. Under normal driving, the rack is off, it is only on when camping.
