I've been wondering what you all would do!!! So exciting! Remember that when you are the person doing the trip, it's fun and exciting. For everyone else it isn't. BUT, that can't hold you back. KEEP POSITIVE!!!
I've done it a few times. It's a challenge for sure, but can also be quite fun.
I love using FB, email, and Skype. That helps a lot. The first few months will be the hardest because you haven't developed your new 'family' of friends yet. So that is something you can start doing before you go. Research places to take your kids (libraries, parks, centers, preschools, schools, etc.). Your job when you get there is to start meeting people. They may not be friends that stick, but it will open doors for you to meet the ones that will. Remember, you get to PICK your new family.
As far as logistics, think about what you MUST have there, and only plan on taking that. Can you store some things with relatives, and have them ship them out to you as you need/want them? We only took whatever fit on the truck.....and that was the largest moving truck you could rent....not a semi. Plan on seriously downsizing. It's quite liberating, too. :)
So excited for you!!! Remember, you have a whole group of ladies (and gents) here rooting for you. :)
