I'm glad you got to spend that time with your pops. I bet the man had some stories. Feel free to share a couple if you'd like to, we're very story-friendly around here. I'm in a very similar boat right now. Back in early March I departed on a road trip with my dog. The plan was to drive from California to the east coast to watch the sun rise on the ocean for our first time and visit many STP friends along the way.
In a bar in downtown Flagstaff with friend 1 the day before St. Patrick's day we learned the world was shutting down. I realized what an awful time it was for this road trip but I was already some hundreds of miles into it and I decided to just keep on truckin despite the news and inconvenience. Found myself standing with friend 4 in the French Quarter at 10 PM unable to see a single other person for as far as the eye could see in all directions, it was surreal.
We kept on traveling. Made it to the east coast, watched the sun rise on the sea. Hung out with almost everyone I had planned on meeting up with and then white-line-fevered it back to California. Here I'm taking care of my very ill elderly mother who can go any day.. or not. Her health is very complicated. Some days I check to see if her rib cage is rising as she sleeps, certain she's no longer breathing. Some days I think she'll go on for years.
I'm grateful for this time with her. I'm just kinda here, putting any plans or desires to travel on hold. I know when she's gone I'll be feeling a lot like you're feeling now. I think the road is a great place to decompress and recharge the batteries of your soul. Stick with your plans, it can't be any worse a time to travel than it was back in March. I don't regret that trip at all. Safe travels. Hit me up if you find yourself in Central California, dinner and drinks on me.
