This. I also pack all of our liquid and aerosol toiletries, scissors and manicure tools in our checked bags too, just to avoid the hassle at security. This whole 3-1-1 thing is ridiculous in my opinion.

Also, regarding airport security, I've flown several times recently, twice from Canadian airports and twice from airports in the US. Interestingly, Canadian airports are no longer requiring the removal of shoes and belts now that the body-scans are being used. The American airports still are.
