When I started my travelogue list / map way back when, I was intent on mapping out destinations to visit where I could have good coffee, good tea, as well as visit roadside attractions and oddities. I actually started a graphical map that I could click on various locations and get the information about that site. But my travel project got stalled, partly because it's such a lot of work!
Enter MapMuse! This is a still-new resource that offers maps showing locations of specific interests. Check this out:
This puppy here shows locations of independent coffee houses across the U.S. Pretty cool, huh? If you click on a dark blob, you narrow it down by region, and you can continue refining your search, right down to the cross streets.
They do have a category for brands -- the perfect resource if you're trying to get into the Guinness World Book of Records by slurping frappaccino at every single Starbucks in every single town in the U.S.
You can also search the category results by zip code, which is always handy. But this is a great service for folx going into a strange city, who don't perhaps know the streets or zip codes or names of businesses to search by.
There is no interest group for tea, unfortunately. YET. I submitted a request for it, especially for locations serving high tea or afternoon tea. Once they add tea houses, this will be the ULTIMATE travel resource.
