I was recently in Columbia and Aruba wished to purchase hurrican glasses but they were not available when I was vacationing. Is there any way I could possibly purchase them through the internet?

If you're on Facebook, there are a number of groups who either trade or sell things related to the HRC. Pins, magnets and glassware are just three, so may I suggest you try there.

I would check their website but I believe if you want the hurricane glasses from a specific city you would need to visit that city's hard rock

I don't think so, you have to buy from the store.
