I'm going to be finishing up a JMT thru over a weekend in July, and, due to the timing of everything, I'm almost certainly going to be traveling for my return trip when ESTA isn't running (Sunday). Since the bus isn't an option, I'm going to be relying on one of the long-distance shuttles to get from Lone Pine to the Mammoth Airport.
I have a decent idea of what's out there, but I'm having a bit of trouble finding feedback/reviews from people who have used any of these services for the most part. Does anyone have any experience/feedback on any of the shuttles listed below?
Original Mammoth Shuttle (www.originalmammothshuttle.com)- Definitely one of the better-looking websites (not that it remotely matters), and the cheapest rate, but I haven't really been able to find any other mention of them other than the climber.org list.
East Side Sierra Shuttle (www.eastsidesierrashuttle.com)- The guy who runs this one is pretty active on the JMT Yahoo group. I can't really find any feedback, but people definitely seem to use him a lot for trailhead shuttling and resupply.
Mammoth All Weather Shuttle (www.mawshuttle.com)- People seem to love these guys on Yelp, but they're a bit more expensive.
Mount Whitney Shuttle- This guy is definitely well-liked on High Sierra Topix, but the website/e-mail doesn't seem to work, and it's not super clear whether or not he's still in business.
FWIW, it's worth noting that I've posted the same question on the JMT Yahoo group and not really gotten a ton of responses, except for the guy who runs East Side Sierra Shuttle.
Also, I should add that I'm well aware that I could wait a day and take ESTA. I'm trying not to do that, because I'm already maxing out on vacation days and my work is already making a pretty decent-sized accommodation for me to do this trip (waiving the normal limit on consecutive days off, letting me go when we're short-handed, etc.).
