I'm not sure about that - that doesn't ever happen to me unless I am riding on sandy streets (or you have tires from the 1950's.) Modern tires, especially race tires, are super sticky. You will flip over before you lock up the front tires.
You live in portland. If you can't lock up your front wheel before you flip a good portion of the time between oct and jul you need to work on shifting your weight around more.
