After last night's Mother Matchup, I promptly put the stock cars away. MrsZtp didn't like this, so she repopulated the roads with mustangs.
The curious thing is, is that the cars in the proper lane (the right) were in storage. So that means she took them out of storage to put them out. Sneaky girl. Also, it seems the police will soon be on their tail. Flee mustangs, flee! [Edit: apparently I'm spiraling into madness and old age, as these cars were already out....so says the missus...]
