Two days ago, Foursquare CEO Dennis Crowley popped the big question to his girlfriend of four years, Chelsa Skees.
 
She said yes!
 
As Skees explains on Twitter, "4 years ago, Dennis and I went on a bike ride that ended with me running away from him."
 
This time, it ended much better. They went on another bike ride on a beach in Costa Rica, Playa Tamarindo, where Crowley proposed.
 
We couldn't be happier for them both.
 
Here's a picture of the ring (Nice work, Dennis!):
 
Here's a picture of the bike ride, from Crowley's Instagram:
