Open Street Mapping Project:

Open street mapping was pretty fun to play with, seeing as how i took a gander at my old town and wondered about. Only this time instead of wasting gas money on finding where Placer Hills Rd ends i can do it by sitting at home at my computer! Which is pretty cool, since i've been living here i've bumped into a few people that come from the same county, and now if i wanted i could show them where all of the hot spots are in town without being there. Pretty convenient!
On another note, i think it would be really fun to assemble a group of friends and just go on a road trip, exploring the different areas in a county since there are so many things places like google and mapquest miss. Also: a collection of backroad shortcuts from locals would be nice....

GPS Revolution:

"GPS receivers require an unobstructed view of the sky, so they are used only outdoors and they often do not perform well within forested areas or near tall buildings."

Well that sucks... so much for mapping my hometown, its completely covered in trees! But i doubt that will be a big problem, seeing as how people use gps in the city and it still reads with lots of buildings around.
I found the Sextant to be really cool (although mostly because it reminds me of the Freemason's symbol) and after about a half hour reading about it i jumped back to GPS.

"GPS receivers can display time accurate to within 150 billionths of a second."

-so does that mean.... that there are watches out there better than the one i have?!??
Answer: yes :)
