First… a little bit about me...
Born and raised in
Wilmington, Delaware
I have a long history with
maps...
I proudly describe myself
as a map nerd…
One of my hobbies was to
draw maps BY HAND…
I worked for AAA making
TripTiks…
for 11 years!
...until they closed our
office :(
So I went back to school to learn GIS
