They'll be doing a host of drag strip events again this year for those interested. I looked at the schedule and it looks like it's $5 for spectators and $15 total to be a spectator and have your vehicle inspected to run on the strip. See the link above for full details.
QuoteThe World Famous $5 Friday Test and Tunes where the track opens on Friday night five times a season and spectators get in for only $5. If a person chooses to run down the track during those nights, it's only another $10 for a tech card. It's cheap entertainment and well worth the trip out to the track.
