try a variety.
get a little of indica and some sativa, and possibly a little with some qualities of each.
indica is more for relaxing in you room in the evening imo,
sativa is more day pot imo.
let the sales clerk guide you, they should know their product.
smoking is always the preferred deliver platform imo, as it's really easy to gage how high you're getting as you go.
with edibles it's harder to gage, since they don't kick in till after the fact of eating it.
edibles are popular because while it's legal to buy there, it's not legal to use in a lot of the situations that's you'd like to enhance.
like anywhere public.
dinning out, (recommend), a music venue, (highly recommend), just walking around, golf.
can't really light up in public discreetly, which is why edibles are popular, as they can be taken discreetly.
don't drive if you haven't used before, have someone else do that.
enjoy each moment and day, and have a great time in Seattle. i'd love to get there myself some day.
