Anybody know where I can weigh a boat and trailer around edmond?

You might check with one of these to see if they can accommodate you.

Edmond, Oklahoma Truck Scales and Weigh Stations for Truck Drivers and Trucking Companies at Truckstops (http://www.bigrigjobs.com/Truck-Scales/Oklahoma/Edmond.html)

I was getting ready to say the truck stops over at 122nd & I-35. We used to use the Petro at I-35/ Eastern to weigh trailers and equipment that we manufactured. We were weighing only the equipment, so we had to pull the combination on the scale first, then pull off and drop the trailer, and pull the truck back on the scale by itself, and then subtract the difference. Grain elevators are also a good place if you are near one.

Salvage yard scale perhaps.

I used the one off of 122 and I 35. I drove the truck until the back tires were off of the scale leaving only the trailer axle on. Then I took the trailer off of the hitch and got a weight. Seemed to work out ok.
