I originally posted this in General Discussion section but this is probably a better place.
If you live in a climate and a city that spreads sand on the roads during a snow, then plows the streets, all that sand they spread ends up in the bike lanes. Sand and pea gravel can be a hazardous surface to ride on when it's over asphalt or concrete. It's as slippery as ice, well maybe not that bad but it offers poor traction. Be careful.
