Is there anything to keep in mind when riding in the snow?

I’ve been riding my bike around in the snow a bunch cause it’s fun, but is there any extra maintenance I should be keeping in mind? I try to keep it off of salted paths but sometimes it’s inevitable. I usually wash the bike down with water after too. Should I be greasing the chain extra? Or taking the bearings out in the rear swing arm/wheels and cleaning them often? Just don’t want to end up with a rusty mess come summer
