Ha! An umbrella with vents! What an idea! I will look for one like that. I assume in case of need it can serve as a miniature tent without posing the risk of suffocation.

Also, thanks for the address. I actually heard back from the company (I emailed them this morning) and they might even send me a new one... which still doesn't resolve the issue of what to do with the old one. So I will check that place out.
