Our plan to make it to Parque Nacional El Imposible before dark seemed reasonable enough. Distance-wise, it wasn’t far and the border crossing into El Salvador went smoothly, leaving us plenty of daylight for the trek. Between the four of us we had three maps and a handheld GPS. The fact that the road to El Imposible was in a slightly different location on each map didn’t phase us at all. It wouldn’t be the first time we used a less than mediocre map (or, no map at all) to navigate Central American roads. We’re experts, we thought. Besides, even if we got lost we had twelve weeks of Spanish class between us – we could easily use our new skills to ask for directions from the locals.
