For those of you hauling cargo trailers/re-purposed kid's trailers/tag-along's, do you take any extra precautions regarding theft protection when it comes to your trailers? Simply a curiosity...I imagine locking up your bike well enough is, erm, well enough...but do you carry any extra locks or other precautions, just in case? I really liked Sixty-Fiver's setup, but down here in SC someone would be bound to steal the tote off the back. Thoughts/ideas/opinions on trailer vandalism-/theft-protection?
