OK I went out during my lunch break to find out what I hit the day before and I couldn't find anything! NOTHING!! Not even some grease on the road!!

I was very disappointed!
Anyway I got home and I completely washed my bike, that grease was nasty, but everything seems to be OK! Tomorrow, I'll take her back to work! I'm pretty sure I must've hit something on the road!
Thanks everyone for your input!
