I should probably start a new thread here, but I fear my question is going to sound stupid or at least naive. Sea grass? I know what it is, but everyone always talks about it in a negative way, like, "you can swim there but they have sea grass" or "the beach is great, but there is a lot of sea grass". So, my question is, is there some inherent danger, or something we should know about the stuff? Last time down, we swam/waded, etc... and there was sea grass, it didn't seem to be a problem... the jellies on the other hand.... not sure ya wanna step on those guys.
