I made string catches on the doors of the traps while Steve prepared his Vangel foot traps which will have to change to day also. I decided to place three traps at the Beach Ridge Vangel foot trap site, and three at the Beach Ridge (Central Marsh) trap site. 1505 The traps here at Beach Ridge are set out.
