Not sure if I'm categorizing this right? Please advise if not.

My two gliders have been with me for the past 6 years, in Northern Virginia. I'll be moving to Portland this summer. I'm concerned about how to manage the cross-country trip with them (we'll be driving) - is it even possible? I'm also concerned about the legality in the states we'll be passing through. Considering that they're getting older, I'm worried about the stress of the drive on them, and the logistics.

If anyone has any advice, or has done this previously, please let me know!

Will you be stopping at hotels along the way? If you do, it would be a good chance for them to stretch their legs. They'll sleep thru the day pretty much. They should be fine in a pet carrier. I would maybe keep the mealies available. As long as they're with you and they have each other they should be fine
