Ha ha, yeah, warning, that's how it starts.

A short section of gravel just as a shortcut.. Then the rear tire slips while climbing out of the saddle and you think to yourself, "A wider tire would be nice.".... Then you find yourself trying to keep up on descents and wondering if 32 mm Panaracer Gravelkings will fit your frame... And it goes on from there.

That's some really well groomed gravel though. Looks like someone was having fun in the left most photo.
