I have used a Nuvi, as well as some other devices and my choice remains Streets and Trips with a GPS (The NUVI can provide the GPS info) S&T 2013 WITH GPS 67 bucks at Micro Center.. I bought the store out (The sticks & Bricks not the internet warehouse) since they had but one.. I have to say the routing is much improved over older versions. I truly liked the route it send me on this trip.
I'm now in the campground where I spend 2/3 of my winter.. Got here just in time.
Generator ran out of gas this morning at 4:30 (no problem with quiet hours, In a church parking lot, and the next door neighbor is a construction company/site) I ran out of water last evening (Drained the water heater so I had enough to use for flushing) and would have run out of batteries about the time I got here. If not for the 20 mile drive from churh to here.
BUT: We had a good choir practice Saturday and I returned in the evening for Mass, then 2 masses this morning (I do enjoy singing, epically that kind) So, all in all, good time was had, and good timing too.
