Flying into meaning literally inside. You can fly among them in VFR assuming you meet minimums for the airspace (3SM visibility, 1000 above, 500 below, 2000 to the side in most areas of the USA).

I have only been in actual instrument conditions once with an instructor who was certified to do so under and instrument flight plan. It's disorienting. It's turbulent. Its impossible to avoid other planes (IFR the tower keeps you separated).

Crosswinds and rain and landing are basically boring after a few tens of hours. But fuck clouds.
