Natalie,
I'm also from Europe and was concerned about crime when I moved to the US. I have lived in Olympia with my family for many years and feel very safe here. If you're looking to rent, you might want to stay away from large apartment complexes and opt for a rental home or condo in a mostly single-family residential area.
Where are you from in Italy? My daughter lives in Italy and I visit there every year. You'll probably experience some culture shock when you move here, and I can recommend a few things that will make the transition easier for you.
1. If you currently live in a small town, try to find a town that's similar in size here.
2. Connect with people in the area in advance. The city-data forum is a great place. You might also want to join the Ft. Lewis Spouses Yahoo Group, or find similar groups online.
3. Urge your husband to request a unit sponsor who will send you a welcome packet and will help you coordinate when you get here.
4. Find places, people and events that let you connect with Italian nationals, and Italian culture, for example here:
Nonna Rosa Cafe Tea Room, New Caldonia, Olympia, WA - Official webpage here. Isn't the Internet great?
5. Find a neighborhood to live in that is not too remote from Fort Lewis and other military families. Military families tend to have a close bond and be supportive of new-comers. This support is helpful if your husband gets deployed or if you need help to get oriented in a new community.
Popular places for military families to live are Dupont, Lacey and Olympia. The commute to Fort Lewis is quick and convenient, there are plenty of shopping, dining and entertainment venues, the schools are good and they're located just a little over a one-hour drive from the Pacific Ocean, the mountains, the international airport and Seattle.
I hope this helps and don't hesitate to ask for more information.
Benvenuto.
Sandy
