A few questions for those who live in Cayey

Hi All,
I'm new to the forum.  My husband and I are currently living in the Virgin Islands and are interested in relocating to Cayey next year.  We like its higher elevation, country setting and relative closeness to San Juan.  We plan to make a pre-move visit in a couple of months.  In the meantime I would like to ask current Cayey residents a few questions:
1) How rainy and buggy is it relative to the SJ metro area?  (here on St. Croix the mosquitos come out in full force after it rains).
2) How is the humidity there in the mountains?  Does it feel like a wet blanket over everything?  Are you constantly battling mold in your house?
3) We'd love to rent a house in a country setting but hopefully still in town.  How safe is it in such areas and can you recommend specific neighborhoos?
4) My husband telecommutes and he requires a fast internet connection.  Is this easily available anywhere in Cayey?
5) With the university in town, are there cultural activities available to the general public or do you have to drive to SJ if you want to do anything cultural?  We're both Spanish speakers, so activities/entertainment in either language is OK.
6) I'm interested in hiking, nature walks, etc.  Is it relatively safe to do these activities alone here?
6) Is there anything that you wish you'd known before you moved there?

Many thanks for taking the time to answer these questions.  These are important questions that can help us further decide if Cayey is the right town for us.
