Great Basin

Hi Folks, I know a nice woman with the National Parks and Recreation Association who is involved with the astronomy festival at Great Basin. Her name is Lynn Davis. I wrote to her asking if people could call her when there was a problem getting through to someone at the park. Here's what she said about that: -- Best wishes, Joe Oh dear, sorry to hear that there seems to be a communication lack. Yes, they can call me [about] the info -- especially if an astronomer is planning on attending. NPCA is hosting a dinner (which is open to astronomers, not the general public ) on Friday early evening and we'd ike to make certain everyone is invited. My number is 702 281 7380. Info is on the Great Basin website, toward the bottom of the page.

Debbie, Try this number; 775-234-7331. Listen to the options, and if you can't get through the front desk, it'll ask you to leave a message. I was able to have Kelly return my call that way last Sunday. Hope to see you there!

Need Rides to SLAS meeting and Jordanelle SP star party
by D P Pierce 18 Jul '11

18 Jul '11

Greetings SLASlings! I want to go to the SLAS meeting Thursday night. I can get to the University via UTA/TRAX. I've been told the next to the last stop would be best for me ( in a manual wheelchair) since that would put me on the uphill side of campus. I need a ride home afterwards preferably after also going to advanced training. I live at 6200 S & Bangerter. It's hard to sleep dodging all those cars! I would also like to go to Jordanelle SP Friday night. I know this isn't to likely since your vehicle will be filled with tellescopes and accessories. I won't have a scope just my foldable 40 lb wheelchair and a bag with a couple binoculars and other stuff. Please and thank you, Deloy Pierce, Large Bored Member
