Well, I am very new to geocaching, but since you are going out tomorrow I will respond now just so you have something to go on. Feel free to disregard if a more experienced cacher gives better advice. On the detail page for a cache, if you scroll down to just above the logs there is a second map and a link that says "view on larger map" -- or something to that effect.
If you click that link, it opens an interactive map page up with the nearby caches marked. At least, it does for me LOL
Good luck tomorrow!
