My gardening companion reported that he saw woodchuck holes galore along the railroad tracks behind our eye doctor's office this afternoon. The kudzu is leafless, so the burrows are visible. He said it reminded him of Matera (and the cave dwellings) in southern Italy.
Hmm, I'm sure that they're not that prominent, but I'll have to go look! He thinks they like the young kudzu shoots as they leaf out later in the spring. We'll see.
