Depends on circumstances,
As stated, under 3000' you just have to be clear of cloud and observe the 500' rule. my airstrip is three miles from the coast with easy landmarks and no hills nearby. I've taken off from elsewhere in the past with very low cloud, knowing that I can fly along the coast at 500' or less and turn in to land with no problems. It helps that as an ex glider pilot, in a very slow STOL type I'd be happy to land in any available space if things deteriorated. In something faster and less STOL I'd simply revise my minima.
