if you run into a big spool of cotton sewing thread for commercial machines buy it,run some lines across trails & ck back to see if its broken,easy & cheap & no worry about stolen camera's.put it out in the late afternoon & ck back until you find it broken,overnite morning or afternoon,please use cotton thread only as the synthectic might stay around & cause problems for kids or animals as the tinsel strenth can be real high,thats my tip for the year \:\) mike243
