Apologies if this has been mentioned:
Be careful anywhere that cars or trucks stop frequently or park. They often drop oil and it builds up into a constant slick patch in the center of the lane.
Here in Mexico the toll booths are very, very slippery at the pay windows for example.
Gas stations. Parking lots spaces and exits etc.
Even if you keep your tires off it, you plant a foot there instead.
It's even worse if your boots or tires are wet or it's raining.
Young enough to know I can. Old enough to know I shouldn't. Stupid enough to do it anyway
