Travelling for a job, is certainly not restricted to IT work. There are many people that either commute each day or relocate completely because they want to do a particular job. If there is a specific role that you are after, then you may need to be more flexible with location than if you are less fussy about what you do.
The chances of having to relocate will also depend on where you live and whether you live near to a place that has a lot of opportunities for someone with your skills.
