An area close to you is the Tailwater access area at Old Hickory Dam. Its on Cinder road. It on my list of sites to check out.
From the map, if there is wind coming from south / southeast if will be coming across the lake.
I did a quick lookup of the kite, and it is similar to one of mine, but lighter. . My Prism Jazz flies in 10 MPH inland winds or above (with longer line) due to the wingspan size / weight. I tried in 6 MPH wind in Murfreesboro and it plainly showed me that it wanted more wind.... or shorter lines.
Keep em in the air, it just keeps getting better. I smiled when you mentioned kites not yet flown. After just over four years of more active flying I still have kites I have not yet flown. Seems they just keep coming to the Kite Dungeon. SHBKF
Those look super convenient! You could probably thread the whole strap through one of the finger holes too if you wanted!
As for recording I was surprised at the quality of the no name action cameras, dinner of which can be got for $50 or even less! I recorded myself with a cell phone leaned against a cooler for awhile too
I am in Murfreesboro. I usually go to Gateway Island. I have been looking for places on aerial maps around Nashville. I have a list, just need to get out and check them out. Also have been scoping out churches with open area next to them. They usually keep the grass cut in the summer time. I have several dual line kites, which haven't all been in the air yet. Two Revolution kites that seem to crash more than fly...but that will change in time.
