I will echo the statement about stocking up before you enter Canada, but be sure what you have meets the test at the border. I have already purchased most of our acceptable items.
On another note, this morning my husband told me that he is having trouble sleeping because he is so excited about our trip. On Wednesday we will be heading out. Before *really* getting on the road, we will be making a stop in Fayetteville, AR for a three night visit with my sister. After that, we will head toward Great Falls and the real adventure will begin.
Other than being in Seward for the 4th, we have no firm plans. We will probably stay in AK and CA until mid Sept or early Oct. This will be our 3rd trip and because of our age, it may be the last so we are going to try to make it a really good one.
