Senior Pass - cost $10, can be purchased by anyone over 62, good for entrance and half-off camping
Access Pass - free to certain disabled individuals, good for free entrance and half-off camping
O, a disabled senior gets both passes and camps free, or 50% off then another 50% off making it 75% in total? I guss that would depend on the math savvy of the gate guy.
Showing my work.
$10 camping fdee, 50% = $5.
$5 adjusted fe, second50% = $2.50 camping fee.
$2.50 is 75% of $10.
Now the less math savvy guy would add he 2 50% getting 100%, thereby getting you free camping. He is also the guy buying lottery tickets to bcome wealthy.
