The cheapest way to quickly discover what an unfamiliar city has to offer is to peruse a postcard rack and buy a few that intrigue you.
Postcards not only highlight “sight-see-worthy” locations, but if language is a barrier, just show the cab driver the picture, and you’re on your way.
Once you’re at your location, write a memory of your visit, mail it to your residence, and add to your scrapbook.
The biggest plus? No need to carry the heavy travel guides with you.
