Living in Canada I certainly know what you mean. Just exploring my province takes time. My first real vacation was taking 2 weeks to drive around the province and I still only saw a fraction of what there is to see here. The rainforests around Tofino have always been my favorite though.
Costa Rica is one of those places that sounds wonderful. I only hesitate due to the language barrier (I prefer to avoid tourist traps, so language is more of a factor in certain countries). Perhaps it's worth another look though. I'll check out that video!
