I grew up in the Springs and remember both the dragstrip and the stockcar track.I went to watch the stockers, but in 1975 I went to the dragstrip for the "Mello Yello Nationals". I remember seeing Don Garlits run. He did a fire burnout and ran 4.10 @ 191. If you go on Google maps, go to satelite, both tracks are still there...corner of Marksheffel Rd. and Hiway 94.
