It was the location that was important. Like Mac, I piled on some vegetation in the middle of the float, too. Used under cover, they worked well during both fall and spring, but in the spring you have more rats traveling so production should be higher then. I do feel using them in places that afford protection for the muskrats from raptors work best.
Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
The Birth of Venus depicts several gods. Venus, goddess of love, stands demurely on the seashell, being blown to shore by Zephyr, god of the west wind. There, one of the Horae, goddesses of the seasons, is ready with a cape to clothe the newborn deity.
