The campaign staff of Republican presidential primary contender Mitt Romney has trimmed his appearances in Maryland in advance of the state's April 3 primary, canceling two previously scheduled events but keeping a town hall at Dewey Lowman American Legion Post 109 in Arbutus.

On the day before the town hall, crews were busy at the American Legion setting up chairs and lights in anticipation of the crowd of hundreds that is expected.

The town hall is scheduled to begin at 4 p.m.

The Romney campaign had announced appearances in Annapolis on Wednesday morning and another in Frederick, MD, in the evening. Both events were canceled without explanation, leaving the Arbutus town hall as Romney's only public presence in Maryland before the primary.

The last presidential candidate to visit Arbutus was John McCain, who spoke in front of a crowd of more than 400 at the Dewey Lowman post on Feb. 7, 2008.
