Here are some work-ups for invitations and handouts for a drive-thru Ash Wednesday service our church is offering. On Ash Wed, during a small block of time in the morning, our Pastor will be set up right outside our church doors offering to put ashes on anyone who chooses.
Normally, folks who attend our Ash Wed worship service in the evening get ashes (which they still can), but only get to have it for a short time before going home, so this gives people a chance to wear the ashes all day.

Ash Wednesday is, traditionally, a time when Christians prepare for the celebration of Easter by spending 40 days repenting of their wrongdoings. It's a solemn time where one reflects on the sacrifice Jesus made. Often, Christians will give up something in their lives (food, extra-curricular things, etc), and replace those things with prayer.
