SKUNK!
The neighbors dog got sprayed by a skunk. In my front yard! It is so strong I can taste it! Eeek! This is the worst smell I have ever smelled. I have smelled decomposing bodies while we wait for them to get picked up, infectious boils being popped when I worked in a docs office, etc. Oh my yuck! My eyes burn. I had my fan in the window pulling air in. Ahhh!
