If you use WunderMap it goes by lat-lon in the URL. If you zoom it in right where you want it and "Save prefreances" that should do what you want. It'll open on your house every time. As you can see below the Lat/Lon is right there in the URL..
The link you posted is giving me some error pop-ups along with my link.
Humm not sure about that but it's possible.. I just set it to Dallas TX since you only give Texas as a location and trimmed off a great deal of the URL (the actual full URL wrapped across 4 lines). I tested the shortened URL to make sure it worked before I posted it. I didn't get any errors, but that doesn't mean you don't, cookies can change how each person see's it. Either way if you get Wundermap setup the way you like it, then "save preferences" or bookmark the link from the link button you should be all set.
Note: as you make changes to the map the URL does not update so you should use the link button on the map it get a new one the way you want it.
