Ride a Bull/Mile High Club
Location: N 40 49.052 E 5 36.702 This is a two for one Easter egg deal. You can find a ridable bull near a beach that will try and buck you off. Travel to the Maestrale area and near the top of the region you’ll see a wreckage, this is where the second Easter egg comes in. In Just Cause 2, you visit an airship club/brothel called the Mile High Club. In the third game, you find the crash site. Check the sign by the bar and you’ll see that the Mile High Club has indeed ‘fallen’ on hard times (pun intended). Right beside this Easter egg you’ll find the bull wandering around. Try not to grapple ride the bull because you can kill it and we don’t want any issues with PETA now do we? 
There’s Always Money In A Banana Stand!
Location: N 40 44.141 E 5 38.486 Arrested Development gets a nod with this frozen banana stand in Citate Di Ravello. This is referring to the episode where Michael and George Bluth are discussing Bluth’s Original Frozen Banana Stand in prison and George screams “There’s always money in the banana stand!!” this one can be easy to miss, the stand looks identical to the shows but it really drives the point home when you blow it up, money will rain from the sky. 
Soap Box Racer
Location: N 40 41.735 E 5 44.023 Free the people in style with your very own soap box car. Well, not really because it doesn’t move, though you can guide it to a hill and let gravity take the wheel. Go to Cima Leon: Centcom and it’s located at an entrance gate. This one can be tricky, if you haven’t completed the Missile Cowboy mission, there will be targeted airstrikes against you and it’s relentless. Liberate the base to spawn the box car. 
If you managed to find any more Easter eggs let us know, there’s so much more to be discovered and I want to track them down to satisfy my inner completionist. Challenge yourself to find them all, it serves as a nice distraction from the main story.
