Pack Flags is offering a pretty sweet deal for springtime.
The "Spring Fever Pass" lets one person (adult or kid) unlimited visits to the park from March to May, all for $39.99.
That's a Hamilton less than the current one-day ticket price for an adult, and you'll get in more than once with it.
Of course there's some stipulations; you have to buy the passes online or at the park before March 8.
Opening day for Six Flags Over Texas is February 28.
