I've lived at the beach for just over a year and have been tagging up the Jax area on wikimapia for almost that long. This site is a fountain of info on all things Jax; I can't get enough.
I liked the article about the Tucson trolleys- my roommate and I used to take the one from 4th Ave to the university, loaded with sacks of laundry, to use the laundromat. The driver would only charge us a quarter and let us off right at the 'mat or our street even though they weren't actual stops. Good stuff.
Our family is hoping to move to the downtown area sometime this summer, so I may probe here for advice.
Welcome Kira!
Welcome!
