In my opinion, The Map Shop in Charlotte North Carolina is the very best map shop in the US. The new owner, Tony Rodono, has been very kind to our Nautical Chart Wallpaper business and has helped us in a variety of ways. I highly recommend him to you, and Tony can be found at mapshop.com or by calling 800-532-6675.
A few days ago, Tony sent his clients this fascinating article. I immediately contacted him for permission to reprint in my blog, which he graciously granted.
Please read it a couple of times and let his wisdom soak in. This is exactly why I started Nautical Chart Wallpaper 14 years ago.
