Whenever "Field of Dreams" came out, he was on a promotional tour with the author of the book. They did a deal where they had a "reading" at Rudder and a book-signing at Olsen.
A few years later when Coster was filming that movie where he's a washed up Detroit Tigers pitcher (can't remember the name), he did some promotional stuff in both Austin and College Station the weekend of the A&M/UT series.
I'm guessing this all took place in the late '80s and early '90s.
Neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord. - Romans 8:39, NIV
