[Talk-us-massachusetts] Talk-us-massachusetts Digest, Vol 72, Issue 1

[Joseph Holmes]

This is exciting. However, I am disappointed that it took 27 months 
after the flight for the data to be posted. I live now in Western Mass, 
in an area recently developed. The 2015 data for here will not be useful 
for my mapping. Arial photos are also out of date. So it looks like GPS 
tracks are all I will have for the next 10 year.

Regards,
Joe Holmes
