Industrial grade gases are sufficient for this application. Anything other than the stuff they bottle specifically for filling balloons (which is sometimes cut with oxygen to avoid asphyxiating kids) will suffice provided it is >=99.8%.

I have the necessary gear to transfill helium and oxygen from the industrial bottles. Then I just need access to a compressor to top with air to get the target mixes.

Many years ago, I drove over the US border on a dive trip, having already mixed gas in several cylinders I was traveling with. Customs officers made me drain them all and spin the valves off so they could take a look inside to ensure I wasn't smuggling drugs or something. Maybe I look shady? Anyway, it was several hundred dollars worth of heliox. I'd rather not repeat the experience. Much better to partial-pressure mix and air top with an on-site compressor, if the option is available.

>> Happy new year everyone! Wow, I just looked it up and that’s 2400 miles each way.  We still have a few tracks/leagues that have not released their 2019 schedules, but the main events have done so and we’re in the clear so far. The good news is it’s looking increasingly likely I can attend. The bad news is I can’t see taking the time away from family for a tow of that distance, and there’s no way I could convince them to come along for the drive (are we there yet?)
>>
>> It so happens my next door neighbor is Jon Tester, senator for Montana. I’ll let the Testers know of this initiative and see if they have any ideas for say media contacts. Is there any practical issue unresolved, analogous to the lack of parking at Tahoe?
>>
>> It should be an interesting year!

He's already invited all sub crews for a BBQ at their place. My wife's cousin served on the board of the research institute, might still as it's been two years since we talked about it,  and I'll be reaching out to Lin. He has several boats and I'm sure he knows people in the area. He's well connected with Rotary Club and is president of a local bank. Another of her cousins was the mayor of Whitefish, MT so he might have contacts too.

>>> Attached is an update on the 2019 Flathead Lake Expedition and the roster as we know at his time. You will be getting an email to join a Dropbox shared folder for the Expedition.  We can use this to share files concerning the Expedition.  Since our last communication we have gone public with the Expedition to the Psub.org list.  That generated one additional submersible that will join the Expedition.  Brian Hughes will be towing Harold, a K-350 Psub from Maryland.  Brian's boat, Harold, is a two man K-350 boat so will be available to take passengers for the science objectives along with Gamma.  Jon Wallace has agreed tentatively to be the Surface Operation Coordinator (SOC) for the Expedition.  Sean Steveson is coming to help with dive/rescue support.

>>> If you have changes to the roster, please update them in the roster file in the Dropbox folder.  At this point the FLBS research boat will tender Gamma, and Josef Crepeau's boat will tender the R300.  We still need to identify a tender vessel for Harold.
