I don't think I'll make it out to the London track this weekend. I have no helmet

Sounds like you all had a fun snow ride.

Ya'll be insane.
The salt burns my veins.
Therefore I will refrain.
The muddy slush ain't worth the pain.

Pyze to clean your bike.. a bucket of hot water works nice.
Washes the salt and crud from your drivetrain.
Just make sure you wipe dry your drivetrain before it goes in the freezer.
The occasional lube would help too.
Last winter I only cleaned my bike 3 times.
Each time was quite the ordeal.
