I'm not good at navigating.  If I haven't been somewhere in awhile be sure that I will be google-mapping the address and taking the directions, step by step.  So I'm pretty sure the best thing the hubs and I have ever bought together was a GPS.  I am in love with this thing.  ETA of arrival, new faster routes I didn't even know existed, being able to program the map so every Starbucks and gas station showed up on the screen, etc etc.  That one about Starbucks came in especially handy when we were on our road trip to Vancouver from Seattle.

Priceless.
