Dave's Geeky Ideas 
It’s my first time visiting your site and I think it’s awesome!
I don’t know if you’ve done it yet, but how about a Back to the Future map? Including Hill Valley, Hill Dale, the school, the clock tower and everything important on the movies.
It’s something I thought about, but there aren’t enough landmarks for a large map, unless I crowded them all together for a smaller section of the city. Maybe just a town square section one day.
Just saw your posters on Reddit! DO BOSTON!!
Seconded, Boston would be awesome!!

I live in Portland, OR… and let me just say that you got the Portland Light Rail system map DEAD ON!! Nice work!
I think it would be sick if you made a true map of Los Angeles based on how they look in either GTA San Andreas or GTA V. Keep up the cool work!
I stumbled on your site today. Awesome work! Thanks Dave.
The Necklace made in Israel and it is handmade.
If you find yourself wanting to buy any kind of knickknack,
be it costume or classic, it is important to remember that just because a chunk could also be signed,
it does not essentially mean it’s more invaluable. Some jewellery creators sign every piece they make,
which drops the worth of a signed piece dramatically.
There are increasingly jewelry retailers on-line now so
you don’t even have to go away your property to purchase Danon jewelry.
For those who desire to buy at an precise retailer you possibly can go to a
Danon jewelry vendor and purchase jewellery, nonetheless chances are you’ll pay extra for it.
Hey Could you make the rail and metro maps of São Paulo – Brazil? Here we’re great fans of geek art!!!
