Visit my Dad & do ceremony w/ Him

I just spoke to Native Father (biological dad) for the first time ever, he reached out to me out of the blue. 
The first thing he told is that he loved me and never stopped thinking about me. 
I thought my Native Dad never thought about me or Loved me.
I cried almost the entire time I spoke to him. Happy tears.
He wants to take me to Rain Dance (A Native Ceremony like Sundance )  near our reservation in Saskatchewan before he dies. He wants us to pray together before he passes. 
His health is failing and he doesn't have long to live. I would love the opportunity to visit my dad and pray with him before he crosses over.
