Five States, five weeks (Northwest)

TourGuide is fairly easy. The word TourGuide needs to be part of the file name and spelled the way I show it. Use Poiloader in the manual mode and set distance. Be careful because you wont want to set it for a file such as McDonalds or you will get alerted all the time.

That sounds fantastic. I would love to do something like that. One thing to be cautious about, as GPS in particular but maps as well can lead you astray, is that some roads, including National Park roads and access roads, are closed in the winter (which can include April and even early May, where you're going). Others are only dirt roads in areas prone to massive snowstorms that may be unsafe unless you have a four-wheel drive vehicle that is neither too small nor too big. In some conditions, chains may be needed or even required. These cautions apply particularly to Utah and Colorado even at the southern ends of those states up against Arizona and New Mexico which you would think would be very warm in the winter.

An example of where people have gone wrong is leaving Las Vegas to visit the Grand Canyon National Park, and they decide to drive to the North Rim as it may look closer to them on the map from Vegas. And they're thinking Las Vegas is 60 degrees in the winter and everyone knows it's hot at the Grand Canyon as it's a desert park. But access to the North Rim, from Utah, is about to be closed off seasonally for six months--they can easily get 100" of snow during a winter in southwestern Utah and at the North Rim of the Grand Canyon. And to drive back around to the South Rim, which is open, from the closed North Rim access road can take six hours in good weather. The distances are huge out there.

Another concern is spring flooding. When 100 inches of snow melts quickly, roads can be closed for flooding.

A lot of information about road and weather conditions can be obtained by checking the Internet or by calling the national park or state highway departments. You just don't want to assume that a road is open and safe because the GPS shows it as the best route or because the map isn't marked CLOSED IN WINTER. A very few people have died but many other people have been seriously inconvenienced by making an incorrect assumption about their planned route off interstate highways in this area.

Wishing you another safe and wonderful trip.
