We live in the 'covered corridor' across Tennessee and northern Miss and Ala. The difference in cosmetic maintenance between covered and non-covered is substantial, as are the opportunities for dock social activity. Spiders are an issue, as are birds attracted by spiders; so we spray regularly for spiders. In my area, covered slips typically cost 150-200% of uncovered, but worth it in my view.
