Suggestion for tieing down in loose sand:

Start with a 24" x24" x 3/4" chunk of pressure-treated plywood. Drill a hole
in the center just large enough to pass through a 24" - 36" length of rope.
Pass the rope through the hole, and tie it off to a 3/8" x 6" bolt. Tie the
other end of the rope to a good (steel) caribeiner (sp?). Dig a hole in the
sand using a camp shovel, sand shovel stolen from that kid in the beach, ice
bucket from Holiday Inn, BigGulp cup, tablespoon, or whatever else ya have
handy. Plant your anchor. Cover with sand. For very winds conditions,
increase the size of your plywood to 36" sq.

Suggestion for tieing down inside a large hangar with frequently open doors:
(ok, so my plane only has a wing loading of 6oz. per sq. foot)

8 bags of cement, one Rubbermaid plastic tote bin, 4 24" sections of 3/8"
rebar, and 8 6" sections of 2" pvc pipe.

Dump 1 bag of cement into tote bin. Add water and mix. Tape over one end of a
pvc section using duct tape. Insert into center of wet cement. Wait one day.
Remove cement from tote bin and knock out tape. The result will be a nice neat
80lb weight block. Repeat 7 more times. While you're waiting, bend a loop
into one end of each rebar, small enough to fit into the pvc pipe. Bend the
other end 90 degrees. Stack your weight blocks on top of your rebar and tie
down. Oh yea, this method works best when you trailer your aircraft to your
flying site with dually pickup truck.
