Gas line antifreeze needed anymore?

With most modern unleaded gas having 10% ethanol, is there any reason to use gas line antifreeze anymore? (seeing as we have 10% alcohol, albeit a different kind, in the gas)

Lived in Minot, ND for 3 years. Never once had a problem with GAS freezing. I also drove the truck everyday. So, condensation in the tank wasn't an issue either. If anything, its diesel that you need to watch. But even then, i think many of the norther areas use a "winter blend" fuel that has anti-freeze/anti-gel additives.

When using my snowmobile. and it's -15C or below I use gas line
antifreeze. If I don't, I risk freeze-up of the carb's and cause
serious damage to my engine. (running too lean).

I think that's a different issue. You're probably forming "carburator ice" which is freezing
the water vapor in the air due to the venturi effect in the carb. One reason not to use a
snorkel in really cold weather (let the engine breathe warm air).
