Backyard Night Time Spring Nature in New Jersey.

Opossum smells the apple second night in a row, but sets the trap off from the outside and avoids getting caught. Actually, I don’t want to catch the opossum since they supposedly eat Deer Ticks.

Backyard Springtime Night Sky Over New Jersey.

One day past the Full Moon. Comparison images taken with a Nikon D850 camera and 80-400 mm VRII lens with and without a 2.0x TC-EIII teleconverter. Both images zoomed to project as the same size. To my eye, the one without the teleconverter is sharper.

There are now two raccoons. I need to set the trap before I start planting in the GrowTowers.

Indoor Springtime Nature in New Jersey.

I harvested about two quarts of Strawberries from my indoor AeroGarden hydroponic farm. I then made Strawberry jam using just the strawberries and Wild Girls Honey from my sister using an Instant Pot recipe I found on the internet. Later in the day I found a Stink Bug on a Pepper leaf. I know they say that the Stink Bugs are vegetarian, I still consider them a pest.
