Ain't that the truth! Too many people have too much faith in modern technology.

Either thinking that their car can go through all terrain because they've seen a similar model do it on TV, or thinking that when their telco tells them they cover 90% of the population, that their phone will work where-ever they go.

I don't try anything with flood waters, that afternoon there was one flooded crossing, and I was able to go around it. As for phones, I have amateur radio comms and UHF CB, the bike looks like an echidna on two wheels, so it'll take a lot to cut me off from the outside world.
