GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

I'll use either but I'm not paying. :)

The idea was to use it to just ride somewhere and then hit "take me home" to get back. But that never happens so maybe I'll start mapping routes out. Some audax would sort that out but I'm not exactly motivated to ride at the mo'. Maybe a nice bushwalk in Oz instead.

my garmin's got the 'take me home' function, although it's still a bit temperamental -- it wants to take me through council estates and back roads. you? not motivated to ride? what's the dealio?
