Never really thought about using it for navigation. My thought would be to have it there for a back-up crumb line just in case.....I currently have an older garmin 76 handheld, non-charting, monochrome I use as a backup. It will navigate pretty well point to point, but I usually just power it up and leave it on the dash to draw a line just in case. I figured that in case I forget the garmin, I would always have my phone, and for the price of the app, what the heck!
Did the SWFL to MA run 2 weeks ago in all that heat. Trailering a heavy 24 footer on a tandem trailer with brakes on all 4 wheels. All 4 were consistently within 10 degrees of each other and 20 to 30 degrees above ambient temp at each gas stop. For instance, in GA at 103 degrees outside they were all between 125 and 135 on the gun. And before the trip the brakes/ hubs were all serviced with new brake cylinders, re-packs, etc. I put grease in each about every 500 miles though I'm not sure they really needed it. Good luck and have a safe trip!
When I got out in the mid 80's, the program was called VEAP and it was a 2 for 1 dollar matching program. If you contributed $100 a month (100 was the max per month) for so many months (I forget what the total max contribution was capped at) you would get a check for $300 each month while a full time student after separation. It was better than nothing for sure, but no where near as good as the programs that followed.
My kids (in their 20's - fish the daylights out of our boat!) saw a demo of A/T today on "Ship Shape TV" and said..."Dad, you've got to get one of those" so count me in and send the codes please. Thanks Wiley
