In the past, other committees that were cash-strapped or coming to the end of their budgets have travelled with representative members from each of the parties. The entire committee didn't go. The support officials went, plus maybe a person or two from each party.
I would like to point out that Bill Siksay, Mr. Abbott, and I live in Vancouver. So if you do it on a Friday, for instance—one can go on a Friday as well as a committee day—you have already cut out three of your travel people.
