Tomato cage help

[jasonig]

Every year I feel good about my set up and then one big late summer storm comes to the northeast and flattens everything. As deep in the soil as I place the cages, the wind topples them. The cages don't bend, it's that they aren't anchored so in late July and August when the plants are tall, they become top heavy and the wind wreaks havoc. When they fall the stems bend and twist. Although they continue to produce once upright, the leaves have been muddied from being on the ground despite the mulch, the stems are weakened and disease sets in. Any ideas how to reinforce the cages to keep them from toppling over? Or maybe a new design? I welcome any thoughts. Thank you.
