New lens
I got a new lens yesterday, and in the current world, I ordered online, and picked up in the parking lot since no customers were allowed in the store. Unfortunately the past two days have been cloudy, but not rainy, so I have been to try it out. Not ideal without sun, but still some nice shots. These are from Quiet Waters (free, but the speed limit still applies, and this afternoon it was really crowded).

Innocence Incarnate
We are settling in for the long haul with COVID-19. To that end I got a new desk chair, since I will be sitting here quite a lot.

| He also goes after one pants leg when we linger after dinner. |

| New chair, hopefully more cat proof. |

This week was supposed to be in Egypt
We were due to leave on Friday, and on Tuesday the trip was cancelled. So we scrambled, and went on a car and camera trip.

Hiking today
Our local paper, sometimes affectionately called the "crab wrapper", has started a Sunday column on local places to go hiking. This week they suggested Franklin Point State Park, and we were off.
