Get a mountain to the mountains

I am sad and need some time in the mountains.  I do not know if anyone would donate to this but I cannot afford to go to the mountains and it's worth a try.  I was thinking if I get enough money I would go to Glacier National Park (I chose this as it is a mountain range the train goes to + I cant drive cause of my disabilities + it has a hostel) and back for $90 each way, and can find a hostel near there for $40/ night.  
If I stay 4 nights there this will be $160 + $90 + $90 = $340 + $30 for me to buy bear spray so I don’t die = $370. I can mostly pack food but I will need to buy some stuff to pack so $50 for that = $420. add $40 in case things cost more than expected / for taxes = $460 which, as long as I did the math correct, is the amount I requested.

Thanks so much!
