Planting in Barrels

Planting in Barrels

After admiring them for years, this is my very first barrel planting. It's a whiskey barrel cut in half of course, but it has no drain hole in the bottom. I plan on growing my heirloom tomatoes in it, and was wondering about how I should prepare the bottom for proper drainage. Should I drill holes? how big? what about layering the bottom with rocks or something? Thanks!! 8)
