I'm glad your dad's okay.
Sorry it seems like people are being dicks, I thought that too until I read through it. Then I realized it's where you're asking. I think a good deal of us here learned to make our living at least partially by not taking no for an answer and figuring stuff out, so there's not a lot of normal sympathy.
You can learn from it though. Your dad was critical once, if it happens again do you want to be in a similar situation? What can you do to prevent or plan for it?
Kudos to working a regular job after the IM success, that always sucks, but you can learn from that too.
For posterity I'll outline what you could have done: First off, the airlines, amtrak, all that, have hardship vouchers. They have public rules on them but if you find the right person they can make it happen. There's some pretty hardcore travel forums out there. Second, there are always people on craigslist looking to bum a long distance ride for free or cheap, there's always people looking for a free travel companion too. I'd also post a few ads offering to trade labor/services for transportation, cash or a ticket. You can also hitch, yes really. Truck drivers also may help out, I'd call trucking companies or try fb trucker support groups and forums. You could also try load transportation bidding sites, look for a load going that way in your timeframe, ask winner if they'll take you along. If you call social services they will direct you to foundations and churches etc. that could grant you a voucher for travel. Ask churches. Try a gofundme or kickstarter. Go beg in chats and reddits. I've got others but they're unnecessary, after 3 days max of hustling the above you should be squared away.
