Yeah, that recalc drove me batshit crazy when I was on the oregon discovery route. There are sections with dozens of roads many that don't connect and the thing would re-route me 50 miles to go 500 feet. I didn't realize it when I programmed the route and didn't have nearly enough via points. But then again, 200 per route and what 10 or 15 routes when you start heading across multiple states on dirt roads you run out of routes quickly. PARTICULARLY since you need a whole nuther route to go the other way Garmin took pitty on me and took my third Nuvi 550 and $150 in exchange for a Zumo 550. This year I think I'm still going to overkill it and I'm going to load City nav, and openstreetmaps on the Zumo, and I'm seriously considering adding a 76c or delorme or a lowrance Baja as well.
