Altitude-wise.
Actually, our first stop was Reno, where we stayed with one of my college roomates. We got in around 9:30 p.m. with two tired kids who didn't want to go to bed in a new place, so Bean fell asleep watching The Aristocats and Bugaboo took a lot of snuggling and crying to finally settle down for about 2 hours before he ended up in bed with us. And of course I stayed up way too late catching up, but it was worth it.
Then Bean had a nightmare 2 hours later so all four of us spent the next couple hours fighting for bed space before Bugsy decided he'd had enough and was ready to play. Sleeping on trips is always interesting, seldom actually restful.
And in my tired state, I didn't get any pictures of our friends and the fun the kids had the next morning. Have to remember next time. . .
Then, we started the 3.5 hour drive down to the Bay Area. It only took 5 minutes before we had complaints of headaches and feeling sick and being hungry. At that moment, we knew we'd made the right decision to fly to NC--one day of travel isn't too bad, but 2 days in a row is just too much for our kids, let alone 5.

We did get to make a short stop in Sacramento to visit my cousin,
Erin and her cute girl, Brianna. We would have loved to stay longer--I'm sure the kids would have been happy to play forever if it meant they didn't have to get back in the car, but we had to move on before the afternoon traffic got too bad.
By dinner time, we were at my brother and SIL's place. We're so grateful that they let us take over their apartment for a couple days. It's amazing how fast our kids can mark and claim a place as their own--they had the whole space trashed within minutes.
Then the next couple days were full of visits to friends:

Friends with new babies,

Friends from our single days in SD,

A family get together in SF,

And high school friends. The only one I didn't get pics of was our fly-by visit to my best friend and her family (where once again, we completely trashed the house in about 5 minutes).
All this visiting has made me a little homesick--and the Bay Area is so pretty in the spring. And smells so good. Even the stinky fish smell from the bay makes me feel like I'm at home.
