For countries, just the USA and Canada, but somewhere in Europe early next year!
For states, my mom's goal is to travel all 50, and it doesn't count unless you spend at least one night there and do some activity. I've been thoroughly through every state from Maine to Florida, west into west virginia, and kentucky, and also over as far as Wisconsin, but I've been to both non-continental states, Alaska and Hawaii. If your counting just stops then also California and Washington state.
