As of now, I'm planning to roll out as usual for 2 weeks starting on June 21st. Same as HINK, as long as gas stations along my routes are open, and food is available, I see no reason not to go. 95% of the time we'll be on bikes in the middle of nowhere.
I have hesitated to start doing detailed routing yet, which is something I'd normally have completed by now, along with hotel reservations. I guess I'll wait about another 2-4 weeks for all that. I had been considering having us spend a couple days in San Diego checking out attractions and museums, but I'll for sure redirect the trip to limit things to smaller towns and wide open National Parks. As of now, that is the only change I'll probably make planning-wise. The worst case scenario I see, short of the country having plunged into chaos of course, is we could also plan to just camp and not go near towns of any large size.
After this situation, I feel like I need that yearly multi-week trip more than ever.
