Surprise Gift for Mat's Bday

Hi everyone! Planning a dinner for Mat's birthday, so please RSVP by March 1st so I can find a place to accommodate everyone.

Shhh... this is a surprise, so please keep it under wraps! Location details will be shared closer to the date once I get a good sense of the number of people.

I want to get him a really nice gift, so feel free to donate however much you want for his birthday (you can also make it anonymous; feel no pressure to contribute to anything).
