In a few days I will be heading towards McAllen, Texas and across the McAllen International Toll Bridge into Mexico with my school bus packed full of household belongings.

Google Maps takes a very reasonable route from Mountain View CA to McAllen TX, basically Hwy 101 to I-5 to LA, then I-10 across the country to San Antonio TX, then Hwy 281 to McAllen. (I simplified this somewhat). Google lists the distance as 1948 miles.

My Garmin Nuvi 360 shows similar routing (hard to compare, the Garmin seems to note every exit and crossroad in its instructions) but shows the distance as 1596 miles.

I cannot believe that Garmin plotted a route that was 350 miles shorter while still using Hwy 101, I-5, I-10, and Hwy 281. Or that Google somehow added the miles up wrong and came out 350 miles longer.

Who do I believe?

Anybody want to try their own GPS plot from 300 Tyrella Street in Mountain View, CA, to 1023 International Boulevard, Hidalgo, TX and see what they get?
