Would another thing, in addition to looking out, be to check NOTAM's for activity ? e.g.....

Scary to watch a light aircraft fly right through a gaggle of gliders earlier today. The gliders aren't equipped with TCAS, PCAS, ADS-B or Mode-S and they all managed to avoid each other by using mark-one eyeballs.
Never quite sure why, when events such as this are NOTAM'd, that pilots elect to fly right into an area of quite intense aerial activity.
