I can see that, I generally prefer looser interpretations to enable those oof the wall creative solutions to problems. Actually one of the reasons I love to play D&D is the creative utilization of limited resources to solve problems.
[tangent]Actually one of the most fun sessions I can remember is a group of lower level (3-5 maybe?) charachters chased by a large, formidable force of goblins and coming across an old abandonded ruin of a castle and having half a day game time to explore it, figure out how best to use our posessions, abilities, and things we found there to try to booby-trap/defend the small army, or at least to minimize their offensive advantage and maximize our defensive advantages. And once we the goblins came running through it seeing how well our various plans succeeded... it was a blast - sometimes funny, sometimes tense, overall pretty fun![/tangent]
