Entrance is free but parking is $12 cash only so be prepared. The museum itself doesn't look to have been updated much since the late 90s early 2000s with faded CRT monitors and many out of commission exhibits.
The sections about biomes and climate appears more up to date (in contrast anyway). All the larger exhibits are locked behind paywalls so don't expect to see the space shuttle without a little extra.
