The city is fantastic, it's the second largest in the country, and where I lived for 11 months. (I can still give you the street address and everything) It's an hour and a half drive to Las Lajas, and it's about an hour up into Boquette, which is a little town (so little you can walk from end to end in about 20min) at the base of the Chiriquí Highlands. David can get pretty hot, I think the hottest I've ever seen was about 109 degrees Farenheit. Downtown's pretty awesome, there's a huge park that takes up the center of it, and people set up mobile shops and such under the shade of the trees. All the parrots in the city go there to roost, so around twilight it's really noisy, but awesome, because they come in flocks of like, 10 or so (when they're usually only in 3's)
