As my brother and I have only taken up duck hunting in the last 3 years we have learned several ways to get by while starting from scratch with equipment. One of the things that I have learned is how to build a semi-permanent blind on the cheap. Last year we constructed a blind along the river with little expense and a small amount of elbow grease and time. Here's how we did it:
a cheap 4' x8' sheet of decorative lattice from lowes $8.00
4 - 2" x 2" x 8' boards, also about $8.00
Jute twine $2.00
Cheap black spray paint $3.00
Spray the lattice lightly to darken the new wood look giving it a shadowy look. Cut 2 of the 2"x2"s in half, drive them apprx. 1 foot into ground for your posts about 2' apart in desired location. Lash lattice to posts, cover with native grass bundles you collect and tie from the area. This will only take about 2 hours. You may also use remaining 2 boards to construct roof frame for camo material or tarp.
This whole deal should take 1-2 men about 2 hours, not bad for about $20 and a few hours of work.
Pass the tradition, introduce a child to the outdoors.
