Formerly an active member of and now the organizer of Portland Lazer Tag (PDX-LT). The group has transitioned from Meetup to Facebook (has its ups and downs).
Anyway, if you like outdoor activities, Lazer Tag is a lot of fun, especially played in local area parks (Mt. Tabor, Laurelhurst & Kenilworth in Portland, and Fir Grove in Beaverton).
I'm trying to scrape up a last-minute game for tomorrow after work (~5:30 PM) at Fir Grove Park (http://goo.gl/maps/xQKko) in Beaverton. We generally meet briefly at the playground on the SE corner of the park for the introduction & then venture into the heart of it.
Cost is $2/ea to defray battery costs (pretty cheap for a couple hours of fun cardio). I provide all the gear, batteries & a brief intro / explanation at the outset. Then we play for a couple hours.
We use Hasbro's Lazer Tag Team Ops gear:
(Playlist with the cheesy Team Ops commercials & equipment tutorials)
I suggest bringing clothing suitable for sneaking / running, possibly getting a little dirty (it is a foresty park / "nature" after all). It never hurts to bring some water too, especially on warm days. And/or snacks.
DISCLAIMER: It's nature, it's a sporting activity. This includes the usual risks, including but not limited to falls, insects, blackberry bushes and other dangers of playing in nature. Use your best judgment. Participation indicates acceptance of these risks and that you'll hold me / PDX-LT harmless in the event of accident / injury.
Sorry, had to say it. That said, the game is really fun and you'll most likely really enjoy it. ^_^
Sorry it's kinda really short notice. Again... There's a slightly longer list of events (which I should probably update) on the PDX-LT FB group.
Hope to maybe see some folks come out. Feel free to join the FB group & RSVP there, too.
