I've never had a problem not sporting a front plate, but living so close to Indiana and most of my driving occurs there, may have a lot to do with that, as Indiana only uses a rear plate.
The only vehicle I've owned that I installed a front plate on is my '96 Ford F 150 and the bumper rusted out in about a year and the plate fell off somewhere about 4 years ago. Always keep it parked on the street and never had an issue.
Although I do love my license plate... I figured out how to post it!
