How do Evangelicals celebrate Pentecost?

Wikipedia sayeth in vague generalities: >In Evangelical churches, where a lesser degree of emphasis on the liturgical year is generally placed, Pentecost may indeed be one of the greatest celebrations in the year.

Christians of these traditions may be surprised to learn of the significance assigned to the holiday by others, and in fact in many evangelical churches in the United States, secular Mother's Day is more celebrated than the ancient and biblical feast of Pentecost Specifically, how do Evangelicals who do celebrate Pentecost do it?
