thanks for the input
much as i suspected ...
we'll just have to close the umbrella everytime after we're done for the day and will have to remain aware of wind conditions when it is up ...
initially, we'll watch to get a feel for what it can handle
less concerned about the umbrella itself as we're buying (i think) decent quality
more concerned about it blowing down due to the base

again, if anyone has experience with the brand we're looking at i'd be very interested in hearing your view.

thanks again!
