In app info of event dino calendar, so you can see what’s coming the next week or so. Preferably time in standard format such as UTC so no issues converting it to correct local time (avoids off by an hour daylight saving miscalculations!) - a lot easier to check in app as I’m sure lots of players rarely visit the forums, especially new players.
Dino’s in rural areas would be good, they seem to mainly be near roads, not in woods / fields
Pokemon style lure for people who live far from supply drops and roads and so no chance of dino hunting when sitting around at home with a bit of time to spare as no Dino’s around the area (also pokemon is good in that you do occasionally get pokemon spawn near you even if you are in the middle of nowhere, similar with Dino’s would be good)
