Was really hoping to finish out my 2024 by doing Ontario to Big Horn to Cucamonga but oof, that did not happen.  Made it to Onatrio just fine but that Big Horn trail is super hard to follow and just filled with bugs. After getting off trail multiple times I looked at my arm and saw that some unknown variety of nightmare bug landed on me. It was big and mean and I tried to get if off of me so fast my Garmin thought I fell and tried to call my emergency contacts. That's when I decided it was best to double back and call it  day.  Add in the fact that I had to park almost a mile away and I put in a lot of extra miles to only get one peak but it was a lovely day none the less. Guess I'll have to go back another time and do Cucamonga on it's own.
