With as many outfitters as there are in Glenwood, that would be the first place I'd look. Get the yellow pages out and start calling their 800 numbers, and ask around. If there's no one there, Denver may be where you'll have to look. A couple of things to consider:
- if the boat's fairly new, you'll probably want to preserve the value as much as you can and a crappy looking patch won't help on that aspect,
- will the extra bucks you shell out for a professional patch job still pain you as much as looking at a sloppy patch in a year or two?
- how soon do you want to get back onto the water?
That said, if you bring it to Denver, Downriver Equipment's right there off Ward Road as you come into the metro area on I-70 and you can drop it with them rather than plunge headlong into the belly of the beast. If you do decide to go further into the city there's AAA Inflatables downtown or Inflatable Technologies down in the south part of Denver. They're all competent shops.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
