If you don’t wanna get mushy then just scroll past (still here?)

As I walk into Wrigley Field for the first time, I can’t feel anything other than eternally grateful. Why?? Because of you, because I promise that without you, we would not be here in this moment. Quite literally.

Passion manifests itself in different ways, but if you’re still here we share a passion that connects, and it’s because of that passion for connection and collecting that’s driven us for 40 years. While we may not have started this, we’re truly thankful for Jim Janeiro and jace.janeiro for offering us the opportunity to be here, and I promise we don’t take it for granted.

I’ll try not to post again tonight (I know it’s been a lot today, but no promises), but thank you all for putting us here in this moment, at this time because it never would have happened without you. Thank you for providing us with friends, family, and community.
