Christmas Chorus, Music Collaboration Singer wanting others to sing w/ (Sandy, Oregon)

I really want to find a Chorus, or someone local that wants to collaborate musically. I love to sing and write songs. My grandmother was a music teacher and had us singing at a very young age and I want to be back at it. I love most music. Would love to work with someone local. Let me know if you want to form something. I near Sandy and Boring but will travel to make music :).
