Hi Tomommie,
I think both communities have a lot to offer. How do you feel about snow?
Also, as others have already suggested, can you come for a visit? I am a strong believer that one knows when they have found their "new home," as it will feel right.
Any other information you can give us might be able to add may help us.
In the meantime, I'd recommend that you look at the Idaho Falls 10 Things to do. Many of us have added to that forum over the years.
Also, I'd recommend looking at the website of Idaho Falls Magazine. There are a tremendous number of resources there.
Idaho Falls Magazine.
Finally, contact Torrie or someone in the Boise area for some guides about Boise.
It sounds like your husband is being transferred. Are there other area employees in each area whose families you may be able to contact with specific concerns unique to his employment (if that is an issue - such as commute time, which can be long in Boise compared to Idaho Falls).
I hope you can visit first. Sometimes there are little things which may be little to some of us but not you, or vice versa. You deserve to be happy in your new home.
Kids are welcome in Idaho!
Let me know if I can help in any more specific way. Good luck in this process.
