Scale of our Solar System and Beyond

 I don't see how my elementary school teachers expected me to be able to visualize this:

A day trip at Powder Canyon

We hiked the well traveled trails of Powder Canyon in Rowland Heights, with some coworkers and friends. Social Distancing was observed and we wore masks most of the time. The popularity of the trail was obvious from the crowds, probably because of it's proximity to the urban forest, and it had easy access from several trailheads.










 

Hiking Box Springs in the Rain: spotting Burros (aka Donkey)

We hiked Box Springs Mountain in Moreno Valley, CA. It was a rainy day with our friend, and some misplaced Burros (from the bygone age of Spanish imperialism). The hills were steep in many spots but the rain eventually laid off and we made it to the top. The trail going down the hill was much steeper, but that meant for a faster descent. A day hiking in the rain is underrated.
