If you want the image to be larger thanthe rollover area, or if you want the image to be in a differentlocation than the image button that pops up, use the Show/Hide AField action. First, you specify an icon for the button that willbe shown and hidden. Next, you create a second button that actsas a hot spot when the mouse rolls over it. You do not assign anicon for the appearance of the second button. Instead, you use theActions tab to show the first button when the pointer enters thesecond button, and hide the first button when the pointer exits.
If you have only one vehicle, it is best to park it near the trailhead where you exit the canyon. Be sure not to drive off-road, block another vehicle, or otherwise obstruct traffic when you park. Valuables should be secured out of sight (in a trunk if possible), glove compartments left open for inspection and the vehicle locked. On the South Rim, the Bright Angel Lodge offers a storage service for valuables for a fee on a space available basis.
