Possible Travel Trauma

I'm sure you know by now about the increased level of security at airports in both the US and the UK. Right now they're telling people at Denver International Airport (DEN) that they should arive three hours before their flight to get through security. I'm flying to Idaho on Sunday at 8:40am. I'm planning on getting to the airport by 5:40ish. I'll post about the exeprience as soon after as I can.
