Our passports expire in November, just sent in our applications for Nexus cards. $50 for 5 years is better than the passport. We only travel to the US, so we don't really need passports to go anywhere else.
The Nexus cards work really great, being pre-approved makes crossing very easy. Needless to say, driving past those long summer border lines is great fun.
